By my logic, TV manufacturers can also charge TV app developers for the use of their IP if they so desire, yes.

I don’t see how that’s nonsense or hogwash. It’s a very basic concept since the dawn of men. You want to use or own something I own or made, then I can ask you to pay for it.

In this instance it’s the frameworks and SDKs that were made and that others want to use.

In a similar fashion, they already extract payment in exchange for them featuring whatever app has decided to pay for that privilege. Don’t see how that’s somehow morally better, nor do I see a legal hurdle.
