Their rage should be directed a little closer to home. It seems that the UC has put monitoring appliances in all of their network and kept both the metadata and the data. All of it, and unless you were using your own VPN rather than relying on the one provided by the university, all that activity as well. The university has a unique MITM presence as all the certificates belong to them.
Supposedly this was to increase transparency. Even more laughable is that there was no transparency concerning the installation of the network monitoring nor its further operation. Not surprising, you need only look to the UC President to figure out why.
