Rules:
not sure but maybe has to do with patents(?) since most companies can hold 20 yr patent terms on thier products in USA and they decided to went with the better side of "why not open this thing up? we already made some money out of it"
Not really how patents work. It does not matter if the code is open or not, others are still not allowed to use patented code elsewhere or at least not commercially. (Not talking about the legitimacy of software patents)
