Remember when Apple bought Shake - one of the leading VFX workflow apps, responsible for IIRC all the compositing on Lord of The Rings, and it went on to become an industry-dominating platform...
Oh wait, no, what Apple did is cancel the non-MacOS versions, hoping platform exclusivity would encourage users to buy Macs, and then another app came up on Linux / Windows replacing it entirely within about 6 months, because no one is going to dump their chosen hardware platforms to get "Pro" software from the toy company. Shake disappeared, becoming just depreciated scraps of Motion and FCP's codebase.
Apple is where purchased technologies go to die.
As soon as the founders get their stock vestment, they cash out of Apple, and there's no one left to advocate for their tech, and someone else comes up with their own idea that gets political backing.
That's Apple's big problem - there's no internal tech strategy. Everything in the company survives on the willingness of individuals to work on it. Aperture, and iBooks Author being prime examples - both Pro apps for their respective fields, both vastly superior to third party alternatives, and both died because Apple couldn't find anyone internally who was willing to own and drive the projects.
The only reason for Apple to buy RED, is for their raw video patents, because RED is going after anyone using PRORES RAW in camera. Similar for Black Magic - their products have been great, except the BlackMagic eGPU, which was an overpriced, stupid product, and more or less designed by / at the direction of Apple.
Apple would ruin either of them.
