No, I expected them to go hide in their little corner of it when the bulk of the population moving here turned out to reject their particular view on reality.

Whether they "founded" the platform is irrelevant, it's an open platform and they're going to be in the minority.

Edit: Oh, and since you switched the goalposts from tankies to "Marxist Leninists", I figured I should point that out. I'm specifically talking about the people who think Russia's full of awesome and manliness and crap like that, rather than being the kleptocratic mafia state basket case it actually is. "Marxist Lenninism" is just a word those people use to sound intellectual.

We joined a platform founded and inhabited by Marxist leninists and checks notes ... Expected them to not support an authoritarian capitalist country. Is that really too much to ask?
