Add to that that for the freedom-concerned user Pocket has to be replaced (Wallabag is good), as do most of their other "privacy respecting" services. There's no advantage with them over any of the propriatary alternatives other than a fallen-out-of-favor-dwindling-financially foundation-corporation hybrid healf heartedly developing an important browser saying they won't sell your data.

Google isn't afraid of bad PR of larger caliber. No normal user cares whether Mozilla is getting money from Google and people who care find it questionable that Google is the default search engine instead of something like DuckDuckGo (that would fit the Firefox brand so much better).

Whenever the day comes it'll be a small notice on the normie-tech websites ("An era has come to an end") and a short discussion in freedom-concerned tech circles.

Who doesn't deep down already consider Mozilla dead at this point? I'm just hoping for a good rebirth.
