1. First off, who's to say LastPass will actually delete my data when I delete my account? Could I in practice be increasing my exposure by starting to use something different?
2. Bitwarden: They look cool but "In September 2022, the company announced $100M series B financing". In my experience, usually, financing = bad.
3. KeePassXC: I'm afraid the UX will be worse. But hey it's in my operating system repos, so perhaps I should just give it a try?
