What’s being proposed is that the extension would modify the page to add a Lemmy frame for commenting. This frame is autonomous in the sense the user must provide his Lemmy login information for it to work, which is different from Google login information. Google is not even aware the page is being modified by an external comment section, and even if it could detect it, it wouldn’t be able to track individual users.
If the company’s private, which means its stocks are not tradeable anymore, what’s the point in measuring the company value at this point?
