This is true and represents the feelings and thoughts of two of three very close friends of mine who work for Mozilla. Mozilla USED TO BE independent but have fallen wholly for Google as their sugar daddy, which is the biggest part of the problem with their leadership/management debacle(s).
Mozilla, as a whole, does not pull down much in the way of profits. They develop FREE software and act a pillar in the open source community. However, the open source community is starting to take notice that Mozilla is floundering, and mark my words, if Mozilla goes over fully to the dark side, the GNU community WILL retaliate by making sure Mozilla burns.
