The main "privacy" use-case with filesharing is purely about inconveniencing merely-corporate adversaries via countries where they can't just demand the data without a crime-related reason due to local privacy regulation. (They'll immediately roll over if there is, no VPN operator will care to go to jail for their users.)
The main use-case for most people is bypassing geoblocking nonsense.
It has always made me uncomfortable when privacy projects align themselves with VPNs.
VPNs are, at best, a tool for rerouting traffic. There are a few good reasons
for choosing to reroute traffic but none of those reasons are about privacy.
And all of those reasons are predicated on an ability to trust the new provider *more* than the default/another.
I'm skeptical of that trust in the best cases, I have no idea how it can be justified when/after a provider actively supports authoritarianism.
