They're not buying devs themselves, they are buying the entire publisher company with multiple development studios in them who were already making multiplatform games for all systems with the intent to try and monopolize. Already have it documented they were trying to freeze out not only Sony but making plans for a hostile takeover of Nintendo.Apple cared.
Its still freezing out your competition from those companies developing for them. Its the same shyt, just smaller scale.
Besides, I never understood why people expect 2 competitive companies to have same exact business model?
Sony buys smaller developers, that they can afford.
Microsoft buys bigger developers, that they can afford.
They are clowns fam with an already documented history of anti competitive practices.
