Again? At this point, I would think the only people willing to use them are the people who don't keep up with this kind of news, which is a lot of people I guess.
The tradeoff is basically copy/paste from password manager, vs input directly from browser extension. IMO, copy/paste clearly exposes the smaller attack surface, because it exposes max one password through the clipboard buffer (assuming no further chaining of exploits to escape extension or browser sandboxes). Whereas a browser extension must interface with the vault, which exposes potentially multiple passwords to compromise by methods only possible when the extension is installed.
(Incidentally, this logic might also explain the popular hesitancy of 1Password users to ~~upgrade~~ migrate to an electron version of the app.)
