I feel like rumble/odysee (I have no opinion on peertube, as I'm unfamiliar with it). Are 'good enough', simple enough to use, and reach a wide enough audience for most content creators. Likewise twitter under Elon probably has secured 'good enough' for social/ micro logging. I was listening to a cultural commentator yesterday stream and that does seem to be the case for many. There's a trade off, they need to reach a wide audience for it to be viable/worthwhile. They were streaming on odysee and we're questioning the future of their video content, having been banned off YouTube multiple times. It feels like people are shopping around still for long-term/stable YouTube alt, in a way that they're not (currently) for a twitter alt.
It sounds like a very complicated and costly problem to solve tho.
