Apple: “Nooo bootROM will lessen our grip on our users! We can’t have people installing postmarket os. Sideloading is dangerous waaaah”

Yeah. It's a matter of national security for them to be able to monitor everything in their app store so they can compete against popular products

Physical access and obsolete tier devices means this will largely just provide a jailbreak method for older obsolete phones and some other, weirder devices.

Someone who knows what they are doing won't need a raspberry pi though. They just used one for their proof of concept and provided that code. Once a real jailbreak is here it will probably be as simple as plugging in a usb cable and running a program.

What's it mean that it targets chips still running Apple's latest iOS? If it's the latest iOS then there isn't a newer version available.

Edit, I read the article. It means it's targeting phones even though they're running the latest iOS

Buying iPhones is a mistake.

You’re right OP, Apple is wrong to provide the longest support lifespan in the industry realm of consumer products

Major iOS versions regularly drop support for older models. They're talking about phones that aren't old enough to have had support ended yet.

In other words it's a matter of financial security for them.
