Is this news to anyone? of course it is! The reason that they don't let you run MacOS is absolutely arbitrary, in support of you buying another device. It also allows them to avoid the cost of supporting MacOS in another form-factor.
This feels more like a facebook post that would shock my mom then a HN article...
I have long wished for a future when I could just plug my phone into a KVM and have a full desktop experience.
Arbitrary is doing a lot of work. With MacOS you can use an iPad as a touchscreen external monitor. Try it and you’ll learn that it’s not a touchscreen OS. It’s not as simple as “not letting you”.
