I'd say they're all relevant but then again I try to set aside my bias and actually gather information that may challenge preconceived notions. This will never get anywhere because no matter how much evidence is put in front of you you'll try to deny it or find some reason why it's simply not good enough without ever really contributing anything to support your claims other than other anonymous users of the internet who have spent a little too much time on this help forum.
Fact is the phones can be hacked..if you've seen what I have and what thousands of others report to have experienced maybe you'd consider that. Why else would there be such a focus on security if it wasn't an issue. "Nothing to see here...move along" much?
Those articles don't talk about the FBI paying for the San Bernardino shooter's passcode like you're assuming without reading them it seems..they're refering mostly to the CIA's stockpile of iOS exploits that have been widely published across the internet with the many thousands of pages of documens dumped by wikileaks earlier this year. They were and probably still are all over the internet. Many thousnands of very authentic looking documents and exploits that many journalistics and people with actual credentials have concluded to be legitimate. Now I know that the CIA is tinfoil hat speak..but any rational person would admit that loosing control of the source code for those programs would enable hackers to weaponize them for their own broader purposes. Even ethrecheck (malware/trojan it seems--don't download--not in app store for a reason ppl) guy said that opensource malware was released a year or so ago (this was before wikileaks dump btw) and that the "mac malware has gotten out of control".
Refusing to accept reality doesn't make it any less...please go read through the 1,274 and counting CVE issued Apple and MITRE Corp. that are iOS specific. Again that number is 1,274. That's One Thousand Two Hunder and Seventy Four if that's any clearer.
Many of them are affecting the kernel and other low level functions... Denying reality isn't going to convince anyone and I personally believe, in the long run, that attitude will be prove to be a major challenge for Apple who has been blessed by the false premise that their devices are inherently secure as more and more people realize this simply wasn't or isn't true any longer. I talk to a lot of people about this and have for a while..for the most part people seem to be adjusting their opinion on this topic. Plenty of evidence exists and one would have to have some legitimate credentials to convice anyone that they're experienced in the topic to be trusted as an unbiased resource. Those who have such countless points on this anonymous internet forum we're using make me wonder what their motivation for spending such a large quantity of their finite existance advising those who can't be bothered to call Apple Care about their issue.
I know what I've seen and not being in denial is simply the first of the 5 stages of grief. I'm truly sorry for your loss. Today is September 12, 2017 as a reminder for those whose watch need winding or ntpdate has been corrupted.
