I am allowed to own multiple computers. Many do. I've got a Linux hand held, a windows desktop, an iPhone and a MacBook. All with varying degrees of freedom and function. I don't feel like I'm constrained right now.
HDCP is an example of the other thing in my mind. It adds zero value to anyone's experience. Any potential value add is hypothetical. You can't survey a person after they watch an unprotected film and receive a meaningful signal. It's pure downside for the customer. There's no such thing as competitive Netflix lobbies.
If I want to run arbitrary code, I'll do it on my windows box or fire up a Linux VM in the cloud somewhere. I don't need weird problems on my phone. If you are trying to touch all platforms at once, try using the goddamn web. I've been able to avoid Apple enterprise distribution hell with a little bit of SPA magic and InTune configuration for business customers. For B2C I just don't see it anymore. You need to follow the rules if you want to be in the curated environments.
