I've been using 1Password since 2008 and I'll be doing the same thing. I have tolerated the UI regressions and even subscription with version 7, but Electron is just unacceptable for what was once an amazing Mac app that put Apple's apps to shame.
I got rid of two of them — Evernote for exactly the same reason.
1pwd going the Electron route would have put me close, but not over the edge — but the fact that they seem to have willy-nilly removed local vaults does.
These days it sometimes feels like one has to write all essential software oneself. Or go back to DOS and plain text files.
They have been talking about this for years. It was not done willy-nilly. There are limits to local vaults.
They're a business, and 97% of their users were already on the subscription model. If you were running a business, and 97% of your users had abandoned a feature that was a headache for you to maintain, would you stubbornly keep wasting time and money on it?
Bitwarden is right there waiting for you.
The only wish I had over the years(and I would have gladly paid for an additional license): a linux client, even CLI would have been fine. I'm not sure which year they started, but what they pushed instead was the announcement of online sync and other things I did not care about, at some point it became hard to even find the regular version on their website.
This was when I slowly started moving to alternatives. With the move to electron and this anouncement here I'm happy that I moved away a few years ago and their clear signal that I am not the kind of customer they have any interest in anymore.
