It's the right direction of course but the concurrent release with Harvard sort of opens them up to antitrust probe tbh. Clearly the admission offices are all synchronizing policy in backchannels (or frontchannels).
But that would be hard to prove. If two gas stations collude to set prices, that violates anti-trust law. But if they just follow suit as they see the other raise or lower prices, that's generally legal, as long as there isn't a secret or understood agreement. I expect the latter is more what's going on here.
None of this has anything to do with antitrust.
