I'm guessing that the university is waiting for an inquiry or inquiries, by the university, the police, and/or more news organizations, to be completed before it says anything or allows any of its employees to say anything.
If the inquiries finish and disciplinary action is taken or a story written, then I'd expect statements in response. If they finish and nothing comes of it, not sure whether they'd respond.
It's a tough situation. The likeability gap you mention between Starocci and Bartlett factors into it, but I think the thing that makes it really difficult is that it seems like the big drivers of this are Ms. Bartlett and Starocci, both of whom are at best are undignified and at worst toxic people. Mix that together and include sex issues in the equation and it's going to get very ugly.
This topic thread is about Cael, and he's caught somewhere in the middle of all this. It's possible he acted by the book on everything he knew about but is hamstrung by university policy right now in terms of commenting. It's also possible that given his lack of enthusiasm for publicity he's happy to let one student paper story blow over without engaging.
And it's also possible his program has become dysfunctional. Syd seems to be noxious and not someone I'd care to spend a minute with, let alone be associated with in any way (while recognizing that I simply do not understand a lot of what makes that generation tick), but it's people like that who are often the only ones who can blow the top off an organization that has gotten out of control.
We really can't know based on the public record if that describes Penn State and Cael. His 4x champ has been popped twice for PEDs (please don't tell me that this NLWC athlete is not relevant to a discussion about the PSU coach, that's wrong for a lot of reasons) and his 5x champ seems to have been a renowned jerk and possibly a criminal. Not good looks but there's not enough info to know if those are the tips of two massive icebergs that implicate program-wide issues, or just a couple of floating hazards without much below them.
