Personally I don't think an article entitled 'the lies of Timothy Snyder' is all that interested in discussing the nuanced historiography of the Second World War's Eastern Front. (it's entirely possible that Jacobin had a different article about Snyder which you're referring to in which case I haven't read it and can't comment) The article I read, however, emphasized the Home Army's antisemitism to an extreme and all but called them collaborators in the Holocaust with the Nazis, subtextually justifying the Soviet refusal to relieve the Home Army as necessary to protect Jews. I'm fully comfortable with calling that article Soviet apologist.That's hardly the point the article was making.. like at all... it was discussing Polish collaboration as a counterargument against Snyder's odd historiographical claims (inherited from Nolte in the Historikerstreit) that brutal mass violence was visited upon the Borderlands by external agents and that this type and scale of mass killing was unknown before the ‘innovations’ of Hitlerism-Stalinism and their totalitarian methods. This removes their agency and obfuscates any history of mass violence in the region during the period during and just preceding Snyder's arbitrary date of 1933, including the mass violence endemic to the region during the chaos just after the First World War.
The author brought this up in regards to the argument about Stalinist-Hitlerist mass violence being a unique phenomenon where they learned from each other and built off each others techniques, rather than situating it in the broader context of the post-war years all over Europe. And the author is talking about all of this in order to criticize Snyder's awkward push of his ideology onto history and resurrection of the ghosts of the Historikerstreit. I really don't know where you read Soviet apologia into it..
