> Qualcomm could simply offer this option on their own and save the acquisition cost.

No they can't. That's like suggesting "the aircraft carrier could simply turn around." The cheap and simple way for a multi-billion-dollar secretive semiconductor manufacturing behemoth that doesn't know how to write a contract for less than a million dollars or to publish documents for the public is not to just change that. It's to write a contract for millions of dollars to buy someone else that can already do that.

Seems like a corporate version of the "buy vs build" question. If it's true that the goal is to become more approachable to students and hobbyists (which personally I think would be a good idea) - then Qualcomm must've evaluated both options and decided "buy".
