I’m not sure why you thought my comment was defensive. It wasn’t in disagreement with you. I was pointing out that legally, because of Apple’s founder status, they have more rights to modify the ARM core than, for instance, Qualcomm or Samsung.
As far as I know both all of the ARM chips that Apple makes are heavily modified to the point that it’s never been totally clear if it is a superset or not.
Have to? No they don’t. Do they think we are stupid? They want to. The CLOUD Act mentioned in the article only applies to data created by US citizens.
In fact the main purpose of the act was to allow the executive branch to enter into information sharing agreements with said countries to bypass warrants here in the US. If you are a US citizen using a mail service with for instance EU based servers there is less protection legally for your emails.
