For me, it is because I have shared folders for credential management for various jobs and it would be way too hard to get everyone to migrate. In fact, I am not aware of any other solution that matches LastPass functionality.

I have changed my behavior to just using lastpass-cli and a self-written Go/Qt GUI wrapper over the CLI - https://github.com/alexzorin/lpass-ui - (only builds on Linux sorry) to protect myself from the problems of the browser extension.
