Breadtube was successful in its initial purpose to make meandering videos on the internet to make fun of the most easily rebuked right wingers. It was always just a spectacle. Sorry to sound pessimistic, but it was always like that.
Unless the videos or podcasts are one aspect of a broader movement, they're just spectacle. I have slightly higher hopes for the Deprogram guys though. They do stuff.
I'm told there's a huge amount of genuine and hopeful leftist stuff on the Chinese internet. So we should probably all practice our hanzi.
