Mozilla revenue 2021 increases 20%
Threads about the finances of Mozilla are always full of criticism and begrudging. Yeah, they take money from Google, and that keeps them alive. Yeah, they would love to not be so reliant on them. This is old news. But while they are alive, and while Firefox continues development, Google have slightly less of a grip on the internet. That is undeniably a good thing. 
Mozilla getting paid by Google is a better scenario than Firefox being abandoned and Google controlling the browser engine space entirely.
