What Greg saw in 2013 were students justifying the suppression of speech and the punishment of dissent using the exact distortions that Greg had learned to free himself from. Students were saying that an unorthodox speaker on campus would cause severe harm to vulnerable students (catastrophizing); they were using their emotions as proof that a text should be removed from a syllabus (emotional reasoning). Greg hypothesized that if colleges supported the use of these cognitive distortions, rather than teaching students skills of critical thinking (which is basically what CBT is), then this could cause students to become depressed. Greg feared that colleges were performing reverse CBT.
