You can boil the logic down and apply it however you want. The fact is that different people have different levels of tolerance for bullshit and VPN users are a large source of it. TOR is also inherently harmless but exit nodes end up on banlists everywhere because malicious users use them to the point that exit nodes are pre-emptively banned in a lot of places because some people just don’t wanna deal with it. The big email providers have a zero-tolerance policy for the same reason; if your domain misbehaves even once then you’re on the shit-list forever because it’s not worth playing whack-a-mole with malicious actors.

Because shared VPNs are also used by malicious actors and some admins just don’t care about dealing with that.

Linux is truly extensible and it is the part I both love and struggle to explain the most.
I can sit at my desktop, developing code that physically resides on my server and interact with it from my laptop. This does not require any strange janky setup, it’s just SSH. It’s extensible.

Any file manager on Linux supports this

I just type sftp://[ip, domain or SSH alias] into my file manager and browse it as a regular folder

That doesn’t really change that it’s one company hosting it. Unless you’re willing to make 10 different accounts because your super-FOSS friends aren’t willing to join each others instances?

Have you tried? Because Proton is the miracle people make it up to be.
