I mean, maybe I'm confused, but this sounds like they closed one method (among others) that could potentially be used to create a backdoor by, I guess, a carrier or OEM.

There's no evidence that anyone's phone was open to remote exploit at any time.

It seems as if you're using a weird definition - "backdoor" just implies that the functionality exists, not that it has necessarily been utilized.
