They are using it as a proxy for "people with low technical skills" (which is a specious argument since it was a friend of my parents who got me into programming and he remains one of the best I've ever known) and making the usual argument that we should limit control of our devices to make it safe for them.
I actually don't have (much) of an issue with walled garden approaches as long as the wall has a gate that is easily opened, give me an OS level toggle with a warning of "Here be dragons" and I can live with it - it's not ideal but it's not a terrible trade off.
It's something Android has had previously (but they seem to be trying to lock that gate) and iOS less so.
How about instead of a single os level toggle you get a trillion dollar company, renowned for their high quality design, invested in providing the best possible UX while respecting the user as the owner of the device?
The idea being that if we put apple in a regulatory environment where rent-seeking is no longer the winning strategy they could be forced to redirect their resources towards competing on customer value instead.
Which is something I find very annoying, because I know a lot of people who are parents (or adults) or grandparents which have greater technical skills than their children.
