That doesn't mean they're lying any time they mention security. Many of the things they do really are to benefit the customer. One of those is having strong locks on stolen phones.
Which means you need to prove both: you are the owner of the device; and that the parts are not stolen. This means serial number on each part (likely already exists), database of individual parts with "stolen" flag, and a secure way to query this before pairing.
Or don't bother with all that, and just prohibit pairing of parts with unknown origin - which means prohibiting all 3rd party services.
I think it makes sense these days for Apple to make phones without much care for repairability. Labor is too expensive to bother with spending hours on repairing a phone. Cheaper to produce new one.
The problem with that is the environmental impact of disposable electronics, but Apple is leading the way and using recycled materials, avoiding plastic, becoming carbon neutral etc.
I think this is the direction the industry is generally going to move towards. It makes sense and stops being a problem when the entire product is recyclable and/or uses recycled material in the first place. They’ve been touting their advancements pretty loudly, but I don’t think it’s getting picked up by journalists.
That's what Apple wants.

How is avoiding plastic better? If you mean by making phone bodies out of metal, that's not better for the environment. It takes a LOT more energy to make things out of metal than plastic, and even though metal is recyclable, that too takes a LOT of energy (high melting point), and for a small item like a phone seems rather unlikely anyway. Plastic is recyclable too, it just isn't done much because people don't want to and it costs too much.

Phones are not "recyclable", and likely never will be. There's far too many different materials in them, which can't be readily separated.
