Like I said elsewhere, it feels like intellectual territorialism (partially wordplay on "intellectual property rights"). They feel threatened by just about any use of anything under their umbrella that they have not yet explicit approved. They want to be gatekeepers not just for the products, but for what you get to do with them. They want to control the market including both discoverability and which business models that may be used. You can see the same behavior most prominently in the movie industry and in how they treat video services and apply their "release windows", including the enforced DRM. Look up bluray licensing too, and how they handle even the patent licensing both for players and disc distributors.
