When are they moving all to freetube or something?

Unless I'm missing something Freetube is a client. So it wouldn't be Jeff moving to freetube it would be you using freetube to watch his content on YT.

I'm guessing you meant peertube instead of freetube and your answer there is "When they can get paid." Making content takes time and costs money and YT pays creators like Jeff for doing it.

I dislike YT alot but there's financial decisions at play here that can't really be argued with.
