What is this

This sub popped on my timeline and Im confused, from what I can tell this sub is praising the USSR, as a Lithuanian with relatives who got doomed to siberia and my grandparents and kind of my parents for a bit lived in extreme poverty having to starve, and I have not a single in my life that lived during the USSR occupied lithuania tell me a single good thing about it, why are yall praising it? Well Im guessing ita to be different and also because none of you or anyone you know lived through it so its easy to say it was good when you cant feel the pain people went through, but except for that, any other reasons for praising it?
