I don’t get your argument. FreeTube is nowhere near as big as Wikipedia or GitHub. Are you not using any free software?
LibreOffice, Gimp, System Informer, Nushell, Thunderbird, Firefox, Steam, this Lemmy instance, Matrix, … I don’t know what to tell you. I can go through all the applications and websites I use and I’ll have a hard time finding some that sell my user data.
Governments won’t see your friend’s private messages and thus not request IPs. They’re fine.
