There is a lot of criticism about the status of googles financial support for mozilla. This is because $56 million of the $66 million mozilla earned last year were coming from google.
Cnet has an article describing some points why google indeed has to much power and influence in mozilla.
I can see the points and agree with them.. mozilla has to rethink their financial model… Being so much dependent from google is not a good thing.
But you have to stay in perspective… at least it’s free and open software. So there are less danger to loose the application at a whole or to get nasty surprises while using it (LESS not NONE).
