In East Germany the last prosecution for homosexuality was 1956 and it was formally legalised in 1968 - in both cases, before West Germany.
In 1989 the East German State was producing films promoting the acceptance of homosexuality. So there is precedent for positive movement on LGBT rights in the Soviet Bloc without Gorbachev style reforms.

I mean, Lenin decriminalised homosexuality in 1917 and sold doing so as part of an anti-religious campaign. Stalin recriminalised it. No reason a surviving USSR couldn't copy Lenin.
I mean to be frank in the East German bits about producing films I wonder how much of that was for any sort of domestic " East Germans shouldn't hate homosexual" way and if a much much larger reason was the East German government believing it could help them recruit agents and sympathizers from Western countries. Sort of like how the Stasi invented out of whole cloth the " The CIA created AIDs to wipe out the gays" conspiracy which is still relatively popular today. In the Aids conspiracy theory part it was from a belief that many Gay men ( especially the White ones who went to the right colleges) were the perfect theoretical source for agents/ info sources. Just by being gay they already tended to have a quiet grudge against their often very homophobic societies, long before any intel agency contacted them t h ey had to get really good at living complete and total lies to virtually everyone all the time, if there were more masculine they were a hidden minority, there were a sizable number in the armed forces and if they went to the right colleges they were frequently able to join American intel agencies/ major defense contractors/ universities where they could either potentially steal research or stir up trouble/ or in various levels of politics and the secret service.
And frankly as far as the Stasi/ KGB were concerned if they found a potential agent they liked and he spurned them they could simply blackmail him for being gay and force him to work for them. Or if they initially worked voluntarily either motivated by money or ideology and later attempted to back out they could just blackmail them into compliance with a few pictures of them with another man.
Hence part of why the Stasi created and spread the false conspiracy theory that the CIA created Aids. A lot of Western gays were already pissed about the persecution they experienced from their own governments for a victimless crime ( Though of course many were also ardently patriotic in one form or another and if presented with a Stasi man would have sooner spat on him then betrayed their countries even with all the ways their country mistreated them.). The AIDs crisis ramped that resentment and anger up vastly. A lot of gay men ( like one of my closest family members) who lived through the worst of the epidemic even if they never caught it could often see in a matter of a few months virtually every true friend or former lover they had in the world ( The only ones they could be honest with about who they were.) go from seemingly perfectly healthy to rapidly sickening horribly in such a way its almost unimaginable and dying mere months later. For a long time no one had any idea what caused it or caused it to spread and besides scams and placebos their were not any treatments at all.
There weren't even ways to definitively test for it early on. And if a patient was lucky/ unlucky to actually find a hospital that would admit him ( many wouldn't) there was nothing they could do and thanks to multiple stigmas they were generally treated like very smelly live bags of toxic medical waste. When they died it wasn't unknown for the hospitals to just dump the body bags in the back alley. In order to say get an orderly to help carry the bodybag into a friends car you might have to bribe them like 500 bucks ( in 1980s dollars) to carry a body bag 15 feet.
Then if said Friend was lucky enough to find a crematorium with a shady enough owner they might have to bribe them like 5 or even 10 grand just to cremate body secretly at night ( So just a few dozen times a normal cremation cost). Getting your dead friends and loved ones openly buried or cremated was pretty often totally impossible.
All the while the vast majority of straight society didn't give a single damn. If they even mentioned the epidemic it was most often a joke about " Faggot Cancer sending those freaks to hell.". During the 8 years of the Reagan administration by a margin the single largest incident involving a relatively high ranking Administration official talking about t h e Epidemic consisted of a press conference where the Press Secretary and some reporters spent about 10 minutes cracking jokes about " Faggot Cancer".
That really bred a very very deep resentment against much of the US, the US gov, and the Reagan admin in a lot of ways. The Stasi took note of that and created and spread to the US ( especially in Gay communities.) and other parts of the West both ti stir up dissent and to potentially lay the ground for recruiting agents and sources.
Its sort of like the " CIA invented crack and spread it in black neighborhoods to destroy black communities" conspiracy theory ( though that one to my knowledge developed organically and wasn't any sort of espionage). It took into account widespread resentment against the US Gov and fear of the damage crack was doing among those communities and developed it into a " The CIA intentionally created crack for racist purposes and spread it in black neighborhoods". Which is more or less completely false though bolstered by a kernel of truth that the CIA for a while assisted in smuggling cocaine to fund covert wars in central America. Though to mt knowledge they never actually shipped the stuff themselves but merely used ties with various Central American groups and Govs to make sure that the Cartel owned and operated planes filled with cartel owned blow were not bothered as they flew across Central America. For that the smugglers paid the CIA a fee. Once they gotten to the Southern Mexican border the cartel shipments were on their own and had to cross Mexico without CIA aid. And not getting CIA help smuggling it into the US let alone getting assistance once inside the US to store it, cut it, distribute it to various cities and then handle internal sales and distribution in the US. And absolutely not inventing crack and helping to spread it entirely out of racist motives.
For the CIA assisting with the shipments through central America were directly pretty much entirely financially motivated to provide dark money to fund the Contras among others.
Crack was invented and spread pretty much entirely out of capitalist motives by gangs within the US. Then and now the real money has always been in providing higher quality powder cocaine to White middle and upper class addicts and recreational users. But the problem is that this constantly left gangs with the low quality dregs of powder cocaine that was difficult to sell to that market and even then commanded very low prices.
Crack changed that and allowed nearly everyone whod si much as flunked out of Highschool Freshman Chemistry to turn what would have been a small bag of low quality powder cocaine that could sell for say 5 or at most 10 bucks and turn into say 10 dime bags of crack which could sell for say five bucks a pop allowing a whole new market slice to be targeted ( namely the poor and working classes) and turn what would have been a difficult to sell waste product into a cheap and hard hitting new form which could be sold for less then its equivalent of even said low quality powder cocaine that was now massively profitable even with dose prices being smaller.
Basically think of Crack as like SPAM. A meatpacking plant/ slaughter house might make most of its money via selling whole hams and bacon while being left with various small chunks of pieces left on the shoulder that are really difficult to sell even at a loss. Spam allowed you to take those various small bits of pork left on the bone after the prime cuts have been taken and combine them into a single canned pork product thats say less profitable per unit then a ham but can be sold at lower prices and much higher quantities to sold making them profitable.
