It’s an unfortunate direction they’re all going in lately.
But for me, the dealbreaker would be no local vaults. If the only place a piece of software will allow me to store my data is on their website then that’s the moment we part company.
But it’s sorta moot anyway.
Because, if you’re using a non-secure GUI like Win10 you’re at risk because Windows tends to leave any plaintext passwords you display to the screen in memory for awhile. And there are sleeper malware trojans specifically designed to exploit that design flaw. It’s something that (AFAIK) affects every password manager running under Windows. And Microsoft has been aware of that problem for a long time. Sadly, there’s still no fix in sight last I checked.
