Thanks. Now I feel obliged to read it...

Perhaps I don't know what "breadtube" is. I knew it only as a reddit sub, on which people would post links to youtube videos generally having something to do with perspectives seen to be on the left of the traditional political spectrum. This was a few years ago. There was no ideological consistency at all. Not much anarchism either. But it was not homogenous. When an anarchist video did turn up it was typically not "shunned and ridiculed" — according to my memory it was more often welcomed in the sub as being unusually on-topic.

I don't know whether my differing perception of it is because "Breadtube" (with a capital B) refers to something else, or because youtube has evolved in some way to subvert it, or just that the community changed since the days when I was on reddit.

Certainly it never steered me anywhere near Stalinism. The Youtube algorithm does not treat everyone equally; perhaps if I'd watched more of the mediocre influencer-socialist stuff it would have done. It's hard to guess what's going on. A more convincing explanation of it would require more reference to specific examples.
