Generally, if you develop exploits, you should be completely aware of every single possible attack vector. If you are working for a company like Trenchant, and you know what you are doing, the last thing you do is use Apple devices (at least fully, most of the time you have a public phone and much more secure private phone)
The reason is, when you take an Apple phone, connect it to a router that proxies through a computer so you can inspect traffic, you can see the vast amounts of shit being sent back to Apple which you have no control of.
Meanwhile, if you do the same with my custom rooted, de-googled android phone that I take overseas, you will see only ntp traffic, and that is only so I don't have to deal with cert issues because my clock is wrong.
