I host a simpler youtube alternative based on https://www.mediacms.io/
It's not a perfect platform, but generally does well enough from my home server and a gigabit fiber connection.
These are good alternatives to have, but a solid chunk of the "youtube economy" is about selling ad time so creators can make a living creating content. I hate ads as much as the next person but we need to recognize that the issue is not purely technical.
That's now on my to-do list, thanks for pointing it out. It looks clean and simple but with some nice features.
