More and/or bigger wars.
No WWI and resultant WWII and Cold War could slow tech in a lot of areas. Aerospace especially.
No, major wars slow down technology due to the huge loss of life and material. While there is often to rush items under development to military use, there is an accompanying loss of R&D on all things deem non-vital. It is a huge net loss, even during the war in development. Then add in the much, much lower R&D budgets (cash, men, materials), and things fall way behind. After WW1, a whole host of technologies being worked on had a 10+ years of lost development due to funding issues - applied physics, radar, engine development, etc. And many of the items that were "advanced" by the war are delayed within 10-20 years of the war. Airplanes and aircraft carriers are prewar technology the RN and others would have keep working on without the war, and probably the RN has both a better ship and better planes by 1930 than OTL. Same for tanks and armored cars. Radar is at least a decade ahead of OTL. Submarines had a similar pause. Same with airplanes. Being broke means low R&D budgets means slow technology developments.

e) After WW1, let the military demand more control over research and science in each country. Just a "military coordinator" at each department could create huge damages to all forms of development.
You could have the "green" movement emerge earlier...
Soviets and Nazis grind themselves out into Stone Age mutual total destruction instead of a slow and gradual Soviet victory.
d) Let the book publishers/authors succeed in with forbidding libraries.
Did they really try? As in, was there a real legal struggle about it in the twentieth century (in the US, I suppose)?
In many countries the idea of public loaning libraries (what we today calls "library") was challenged by authors and authors organisations, just as producers of computer games have tried to forbid owners from selling their used games. But yes, that was as far as I know a 19th century thing, and far from global.
However, it should not be impossible to create a movement in the early 20th century. An alliance between publishers, newspapers (the dominant medium for news and politics before the 1920s) and conservative politicians aimed at libraries that fostered socialist thought, damaged the sale of newspapers and books - added to the Versaille treaty for globla reach. It would not be easy and probably have exceptions (schools etc) but each year public libraries are non-existing damages technological advancement.
I'm not so sure about that. What reasons are their to develop aircraft tech beyond a glorified toy without the First World War? Or are arms races and cold wars acceptable?
Now, now. the Greens out of a radical fringe are NOT against tech, but against wastefull, poluating, etc things. Clean techs are a part of the greens's ideas, mind you.
Let us not get to rightwing pundits idiocies.
Yeah my family has been heavily involved with the green movement since the 1970's and I'm going to disagree with you. The precautionary principle if taken seriously would have retarded pretty much every technologicial development of the 20th century.
