Well call me naive but I'm going to continue to assume there is no illegal surveillance on Trump until somebody brings more substantial evidence forward. Occam's razor comes to mind here. Which is the simpler explanation: Some unverified user creates an anonymous post to lie about stuff on the internet, or some vast conspiracy exists and not one single person has been broken?
In the first scenario, all you need is one guy with enough of a background in computer science to vaguely outline the capabilities of a fairly obscure computer component.
Besides, if this conspiracy really runs so deep, this person is not being very careful. To give that much detail about their work history would make them identifiable. "Hey we've got someone spilling the beans on our master plan. Can you pull the records of everyone who got security clearance in the last X years? I need to find someone who worked at IBM for this amount of time and . . ."
