Okay, so list which websites I can use to watch all kinds of content that I can find on YouTube.

Vimeo? It's basically dead. DailyMotion? It could've been an alternative, but they've recently deleted most old videos. Peertube? Nice idea in theory, but lack of content.

Facebook, Instagram, Twitter, and Tiktok all fulfil the 'whatever topic I am interested in this second, there are videos about it' property, though admittedly they do not have near as much meritorious long-form content as YouTube.

is use yewtu.be from time to time on web, and pipepipex on android.
