That's almost definitely not happening.

I wouldn't be so sure. I don't know about Substack but afaik Patreon has deplatformed people for political reasons before, including anti-imperialists.

So it would be huge for them to lose chunks of creators' revenues if those were to leave over political differences.

This is a very naive argument, in a way akin to the liberal notion that the market regulates itself because if corporations behave contrary to what people want they will lose money.

The idea that corporations will allow free speech because it's in their financial interest to do so just doesn't conform with what we observe happening in reality. Oftentimes political pressure placed on platforms by governments, media and powerful lobbying groups is stronger than the economic incentives to resist that pressure.

Yes, I mean Patreon and Substack. I won’t be surprised if payment processors stop processing certain channels some day, because they’ve done it before. PayPal, GoFundMe, And Patreon Banned A Bunch Of People Associated With The Alt-Right. Here's Why.

I agree with you on Patreon not being worth much of anything beyond the actual user content. But Patreon is not ideologically guided; it's just a lib tech company looking for a way to skim a little money. Whatever notions of Freeze Peach they claim to care about will wither the moment the ADL threatens to call them anti-semetic or funding khkhkhamas. The Patreon C-suite knows that banning a few publicly smeared lefties will cost them less than ending up on an ADL boycott list or getting tiktok'd.

She's not especially impressive, I just can't help but pity her being continually hung out to dry in increasingly degrading ways by the systems she keeps trying to work within. A person in her position could live an easy and comfortable life like any other DC suit passively toeing the liberal line. She burns all her bridges with the DNC to be Sanders' press secretary after they've already fucked over Sanders once before, and Sanders turns around and disowns her when she doesn't endorse Biden. She can't get work in DC, so she uses some of her only remaining relationships to try to make a living as a podcaster by attaching herself to a Chapo host at the height of their success. The Chapo host gets outed as an alleged sex pest and ghosts her, with the scandal sinking the podcast. She gets a job as a talking head on a DC tabloid rag's pivot-to-video internet talkshow where they make her interview a settler colonist promoting an ongoing genocide. Gray stays professional throughout the interview, and they fire her anyway, not for anything she said, but because they didn't like her alleged facial expression after the settler accused her of being a rape apologist.

Obviously she's a privileged imperial reformist whose politics are nothing special, there's just something surreal about how disproportionately her career seems to keep getting worse every time she fails to seig heil with enough enthusiasm. If anything, she's a living morality play for every DSA-adjascent professional "progressive" reformist: you can do everything "the right way" and this is still the best you can expect.
