For Twitch and other corporations it seems like it's not the "right of association", but more the "sin of association" that makes them heavy handed towards individuals with banning, censoring and demonetizing:

The extreme social media dynamics somehow holds these corporations accountable for any wrongdoings someone might post on their platforms which is impossible to prevent or moderate in a timely fashion. They respond with more sophisticated and sweeping algorithms that lead to self-censorship by content creators and unexpected actions like shutting down the demoscene event a few days ago.
