Ah yes nothing says “It just works!” like turning off all but one monitor to use VRR/Gsync.
Aside from torrent the other p2p where an open port can be important is Soulseek, you could be blacklisted by users from downloading pretty quickly if you don’t/can’t share music.
I switched to mullvad a few months back and what I noticed coming from AirVPN is how much less captcha requests I get, I’m not much into p2p so I’ll probably stay with them.
It’s nothing exclusive to open source. Eve Online removing boot.ini and bricking Windows installs was hilarious.
