I am confident they will be. . . and I think the vast majority of people would never be affected by these vulnerabilities.
I recall that the government could not even open an older model iPhone 5c owned by the San Bernardino terrorists just a year ago. That does not give much credibility to these current claims. That iPhone could have been quietly opened without all that hoopla if what is being claimed now were true about being able to get into a locked iPhone. These agencies were under orders to cooperate and the CIA was brought in, as was the NSA, due to the potential for foreign connections.
I believe they have developed malware that could compromise iOS devices. . . but they have to get it ON the devices. I also believe that they can compromise a device before it is delivered. . . if they have physical possession of it before delivery, which is what was done with Angela Merkel's iPhone. Remote compromising, however, is another issue. I also do not believe they have been paying Apple to maintain any vulnerabilities in iOS, a backdoor, so they can keep their accessibility open as some have hinted. Apple's credibility with the Enterprise and its individual customers is far too valuable to ever agree to such a nefarious arrangement.
Unless that whole episode was a feint to give potential targets a false sense of security.
