BuffaloStance their free tier is far too limited
gee, I wonder why? The VPN market is already a hard sell, especially with so many scammers out there or companies that rely on false advertising - and that's a lot of competition that has way more money on their hands than Proton. Having a free tier (no matter how limited it is), is a big bonus for me and definitely not a negative as you make it out to be. Nobody owes you (or anyone else) free stuff.
