Nobody wants a browser that's focused on diversifying its revenue, especially from Mozilla which pretends to be a non-profit "free software community".
Chrome is paid for by ads and privacy violations, and now Firefox is paid for by "AI" companies? That is a sad state of affairs.
Ungoogled Chromium and Waterfox are at best a temporary measure. Perhaps the EU or one of the U.S. billionaires would be willing to fund a truly free (as in libre) browser engine that serves the public interest.
