Twitch has the issues the other commenter described, and both Twitch and Facebook are owned by billionaires who are actively collaborating with the current authoritarian regime. Facebook in particular is a risk space for actually exercising free speech and giving coherent critiques of authority.

Dailymotion is... maybe okay? As a company it seems like it's on life support. There's a "missing middle" between the corporate highly produced content that's distributed across all platforms and being a long tail dumping ground. I did find things like university lectures there, but there isn't creators actually trying to produce content for Dailymotion like there is on YouTube.
