Things are different than the mid 90s. There are plenty of schools teaching computer science well. I think a school has a responsibility to its current/incoming students to give a quality education, and the UC system does that at a greater scale than any other top universities.
I graduated this past May, and let me tell you that TAs are struggling, pulling 40-60 hour weeks of pure TA work plus whatever classes they need to be taking to handle the sheer scale of these CS classes (800-2000 students). 15% of the undergraduate population (32,000 students) is graduating CS or EECS. You can't just keep scaling up class sizes and undergraduate populations forever, and the fact that Cal is getting this criticism for doing it at a level far above any other top CS university is surprising honestly.
