I live by Windows+R for the run dialogue.
If you populate %userprofile% with shortcuts named after keywords to your commonly used apps (eg fire.lnk for Firefox) then you can just slap Windows+R, type fire, Enter.
Yeah I agree it’s been an extreme reaction. Perfect is the enemy of good. Maybe most proton users will be willing to seek out even lesser known alternatives and even self host. But if you’re going to talk to a casual user about getting off of Gmail and then you say “Oh but not Proton” then they’re just going to stick with Gmail.
