I dabbled earlier but started using 1Password in earnest in 2010 or so with 1PW3. There are plenty of things that could be argued about when it comes to the switch from a native Mac application to Electron, degradations in the GUI etc, some of us may be more sensitive then others. But one major objective thing you're apparently missing was the shift to a forced subscription, including deactivating previous supported sharing methods, and with the typical-for-VC-driven-feudalism-model eye wateringly, outrageously expensive and inferior multi-user support. Pure, proud rent seeking. And then naturally as well the artificial segregation of simple features like custom templates began too.

I hope someday that's made illegal. In the meantime there's Vaultwarden.
