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.
Pick one that has a wireguard config generator, so you don't need to use any client software besides the normal linux wg client.
I'd also look for one that accepts anonymous payment methods. Even if you don't intend to go to the trouble to use that yourself, it's probably a good sign if it's available. Mullvad is pretty safe and served me well until they stopped doing port forwarding. Proton, windscribe, azire, and airvpn were the ones that seemed most recommended when I went to look for a new one a few months ago.
