You're adding emphasis wrong. And you completely misquoted the article!
First of all, the first sentence of the article says unambiguously:
[Apple] is blocking the use of unauthorized third party Lightning cables with iOS 7
Your quote comes from a couple lines down:
There is word going around that some unauthorized cables with cracked chips have been working with iOS 7. Apple will probably shut the door on the usage of the latter in a future update.
OK, inappropriate use of the phrase "the latter" but in context it's pretty clear. TFA says that Apple is currently blocking "unauthorized" cables, but despite this some unauthorized cables with "cracked chips" may still be working. Of course, since iOS 7 is blocking unauthorized cables it stands to reason that Apply will try to disable unauthorized cables that use "cracked chips".
Whether they will be able to do so is kinda irrelevant to the main thrust here which is that Apple used an operating system upgrade to lock out third party cable makers. Wont someone think of the poor airline stewardesses!
IMHO, this news is just piling on considering the fact that your iPhone uses a custom adapter that is incompatible with all other phones, costs 5 times as much as it should, and will be forced into obsolescence after a few generations.
