At this point "my phone" is a pretty meaningless distinction. It's just Apple's phone as a service. For whatever reason people have drawn this, to me arbitrary, line where it's decided that it's not your MySpace page or your Squarespace site just because someone else distributing it on your behalf but once you hold it in your hand that rule can't apply because reasons.

It's been a decade and a half of software not being the user's agent and instead some company's agent that in some cases you buy the hardware for.

Unless how we talk about software changes this is just the world we live in now. How many apps do you have that are genuinely extensions of your intent as a user and not company kiosks? Of probably about 100 apps on my phone I think I have maybe 5.
