I think it’s fine if used in moderation. I use mine for doing the mindless day-to-day stuff like writing cover letters or business-type emails. I don’t use it for anything creative though, just to free myself up to do that stuff.
I also suck at coding so I use it to write little scripts and stuff. Or at least to do the framework and then I finish them off.
I think maybe Multihop is the Mullvad equivalent?
