IBM is moving to Firefox

The big corporations are usually very conservative and in order to change something inside the huge bureaucracy people have to go through many obstacles and justify their decisions.
I wonder how ones could justify that IBM is moving to the Firefox web browser. Whatever the justification is I believe it the positive decision for the word-wide-web and normal people using the web.
Do the corporations still have a passion and not only the financial benefits? Maybe both: complementing each other? That would be an idealistic world.
