@fanbaby: Part of the problem (in my experience) is quality control -- taking a 'jewel' from someone you don't know might well turn out to be made of paste, or even worse contain arsenic that poisons everything.

At least if a big company releases something open you can have a higher level of confidence that the quality will be good without having to spend the time performing your own quality control.

Additionally, larger companies tend not to use the latest GPL which I have come to dislike for being too dictatorial (and therefore less 'free', ironically).
