One has to wonder if they just split off adult content into a separate platform using the same Amazon logins, and including cross-platform notifications one way from the twitch site to the adult site whether it would solve both their cash flow and advertising problem.
Or just buy Onlyfans. 😅 For Onlyfans it'd solve their payment issues: Amazon allows using it for payment, and Amazon is big enough that Visa and MC cannot just threaten it.
