I am not affiliated, not paid by them, and don't know anybody there; so I am fit to say this. Adobe is a force of good and very much committed to openness.

Anyone who runs Firefox and bashes Adobe is just being a troll, if not a vile hypocrite. They're doing their part; sometimes they're slow to act, because they're a dumb tool vendor at heart, but when they get around to it, they tend to do good things.

No one should take the credit for Adobe's openness other than Adobe itself.
