iirc part of the deal was exclusive access to their tech for their investment or something

To quote my other post:
Looking into it, there's rumors Microsoft will also get 75% of profit until they have obtained 49% of their investment. So there may be an expectation of profit, which is what I'm questioning.
Which would make sense, since access to their models isn't worth 10 billion but 5.1 billion is much more reasonable.
