I pay for Proton but still hesitate to move passwords there because I could easily see Proton developing a penchant for sniffing their own farts.
I JUST fucking moved from 1PW to BW and super irritated at the prospect of moving again so soon. Sellouts.
A lot of my friction moving from 1PW to BW was due to TOTP (2fa codes) being stored inside 1PW.
So now that I have those codes in a different service than my password manager, I hope it's a less painful process as you describe.
