I recently switched from mullvad to Mozilla and it's been a smooth transition. I don't worry that much about some logging because I just need something to connect my torrent client to so I don't get a letter. I used to have a subscription on mullvad but they got rid of recurring subscriptions like last year, and when I went to change my payment method I got locked out and forced to use one time refills.

I don't like that they force you to use their app though, so I'm still shopping around for alternatives that can just give you the ovpn or wg.conf since an all obviously can't be run on my router or my synology
