There's a chance I'm mostly just being hopeful, and you're right in both that Trump would totally support doing something like that, and that the intelligence agencies aren't a single entity.
>>For me it checks out - leaking informations sounds like something that Trump or his supporters would do. Why would not they, if they have the option to? Per the intelligence agencies - are you sure that they are a single entity, where people are of uniform opinion? And every single person follows law to the letter of it? There is the example that those services employed Snowden - if the services were so organised as to avoid such hacks, we would not have heard of Snowden.
But from my experience in other government entities, I believe that doing something like hacking into someone's phone, would require approval and support from high enough officials in those organizations, and so far it seems that these organization do still seem to remain professional and not involved in political actions by the president.
I agree that there might be (and I'm assuming there are) private Trump supporters in those agencies, that for example, would do 'a Snowden' and release classified and private information that they shouldn't. But that information first needs to gathered, and I don't think Jeff Bezos has done something to warrant previous gathering of information about him.
(If information about Trump for example is released this way, it would seem more likely to me, because we know they collected that information while thinking he might be a spy).
But once again, I hope I'm not just being hopefully optimistic in my trust of 'the system'.
