At least two members of the Academy leadership went so far as to suggest that the organization should apologize to the FBI for offending it. One opined that he didn’t think Roy, a full member of the Academy, should be allowed to present at all.

Like seriously, apologize for what? Hurting the feds feelings? Merely having a guy suggest that the feds may be (they do) jailing innocent people?
The reality is that even if we go full idealistic true believers that think that the system works as it's described and intended (assuming the US justice system), the whole justice system really doesn't have the resources to go after every single person, and would rather go after those that they can be sure the charges would actually stick.
It's kinda the same way with where if every single person accused of any crime refused to take a plea deal, and went to trial, the entire system would be bogged down to the point of being non-functional.
Payment info could easily be stolen cards. As for IP addresses, those can easily get semi regularly rotated around, and I highly doubt ISPs are in the business of keeping a history of who had what IP at certain dates.
