I'd still rather not let anyone have the encrypted versions of my keys/passwords. If the software is compromised then it's reasonable to consider the encrypted data can be brute forced with some time.
I'm not here to argue the merits of encryption. I understand it very well. I'm only considering my own levels of comfort and need to trust a 3rd party as well as pay a recurring fee to store my keys/passwords.
Encryption that can't be brute-forced within centuries, even with a quantum computer, exists for some time, and is not really expensive to apply, especially on such small scales as a password database.
