(Disclaimer: as a Mozilla employee, that includes my salary :)
a) the "deal" with Google had never happened, and
b) Microsoft came out of nowhere and began offering to pay what Google is actually presently paying (or, let's say, just for fun, even double or triple that), all while
c) Google were making no offer to start paying
... then Google would still be the default search engine in Firefox, regardless.
The same almost definitely cannot be said today.
I'd love to support Mozilla as much as possible, but no way I'm keeping the default Google-search when you have stuff like DDG around.
Hopefully me wanting privacy doesn't impact Mozilla's financials too hard. Firefox + DDG only seems like the most natural combination: both are powerful and privacy-centric.
Disappointing.
The slogan on their page ("Committed to you, your privacy and an open Web") sounds hollow when considering this and their recent support for DRM.
That means they actually need donations for the foundation to run (but its not 800 employees so its much less money). Legally you can't fund the Foundation with the Corporation money - since that would make 2 Corporation and zero Foundation then :)
I don't know if the opposite is possible (send donations from Foundation to the Corporation) but I suspect it has the same problem/effect.
