I ask because I did not use the term "abuse," as that's subjective. Circumvent was picked precisely because it was a clear run around the intent of the program, without the value judgement.
The keyword is "Day 1 CPT" if you want to learn about the abuse.
Certain colleges basically knowingly wink wink and allow incoming students to go immediately work under CPT.
I know what "Day 1 CPT" means and am specifically curious about real abuse of the system at Cal.
In my opinion, it would have to be obvious and fairly extreme to take action over, because there are issues that dwarf whatever impact it might have, the top one being bureaucratic bloat. If 90% of the non-teaching/researching staff at Berkeley were replaced with CPT abusers, I think it would be a net positive.
