I'd prefer to get a VPN to avoid the risk of my internet getting shut down, but I'm not aware of what the options for Linux are. I figured this would be a good place to ask.
Proton and Mullvad have the best privacy record, but I want to suggest a different tool. VPNs are really only useful for tunneling and adding an extra layer of anonymity, there's no total assurance they won't rat on you or get breached.
Real-Debrid is a way to torrent without risking ISP shutting down. Other debrid services exist, I just prefer real-debrid. The debrid service does the illegal part and you download over high speed. It's also more available since you can think of it like a very large scale seedbox. There's also implementation for most media center apps.
I'm a Proton slave, all my eggs are in their basket so I'll go ahead and provide some free marketing for them. ProtonVPN is pretty good since it's ran by a good company that cares about you, getting Port Forwarding setup on Linux is a bit of a chore but I believe they're working on automating it, the Windows app does have it automated already by the way.
I do worry about the long-term practicality of ProtonVPN because of this manual process, since as far as I can tell there's no way to automatically hand your assigned port to the torrent client...
The only VPNs which are not owned by marketing companies are Mullvad and Proton. The largest VPNs are owned by Kape Technologies, renamed because their prior company name distributed malware, whose top people are former Israeli military, so I wouldn't trust them as far as I could throw them. I would never use a free VPN except for Proton, and Proton's paid VPN has a lot more nodes and features.
