Reading the article it explicitly says if CPT is designed as part of your program of study that you need to complete to satisfy the degree requirements, they are fine. They just won't approve it for optional internships. That's what Optional Practical Training is explicitly intended for, Optional.

And no, to be clear, you are totally mistaken about "school break" thing. In fact, you have to be enrolled in credits to get CPT, not on a full break (this is in no way a new rule.)
