monkeytype. That type.biz website has no source code available, and is a lazy copy of monkeytype that is in violation of the GPLv3 that it's licensed under.

Though I am with you in hating Western Big Tech apologia, I don't agree with this point overall. Even the sources you linked show that TikTok collects an ungodly amount of data on its users. The Clario study shows that it's in 6th place... is being lower than Facebook and Instagram supposed to be an accomplishment? And it's much higher than Twitter and Zoom, which is definitely not a good thing.
I've always wished that social media sites would have their algorithm be user customizable through some kind of basic syntax. There could of course be a default - but the user would be able to see what it is, how it works, and be able to customize it to their liking. Of course, this would be complicated, but it's not like these algorithms don't already exist. They're just hidden.

If you want a more minimal solution, you can use the library with mpv. https://benad.me/blog/2018/05/08/watching-youtube-and-twitch-with-mpv/
I found it from the Privacy Guides "social news aggregators" page. It describes Lemmy as a fediverse-compliant Reddit alternative, which sounded really appealing to me. I joined pretty quickly after that.
Edit: looks like they removed it a couple of days after I posted this lol. I guess that makes sense, given PrivacyGuides is meant explicitly for tools that are designed for privacy, supporting encryption and such. Any social media doesn't really fit that. You can see the discussion that lead to its removal here.
