Although I value privacy, I value sustainability more. Choose an option you feel most comfortable with, option which puts the least burden on your shoulders.

My thoughts exactly. I use Bitwarden and passkeys sync flawlessly between my devices. Password managers tied to a a device or ecosystem are stupid and people shouldn’t use them. This is true whether you use passwords or passkeys.

That said, we cannot blame users for bad UX that some platforms and some devs provide.

You are right, op uses the term incorrectly.
