You sound like the kind of person who, in the 90s, would have defended Microsoft against GNU and Linux and the FOSS movement as a whole, "This is the way the world works." No. I was using Keepass prior to Proton Pass. Proton proved to be a downgrade in every way. As a company they are in the same bracket as Ubuntu - trojan horse style grifters who wave juuust enough open-source around to lull users into dependency on a service that overall does not support user freedoms. They are grifters. It's the same playbook as Google.
Software needs to be free on every level. It's fine to sell free software, but if any part of it is proprietary, it's as the FSF says - it's a tool of unjust power over you.
And I don't need that. Better alternatives already exist. Proton was straight up a downgrade.
