We also had expensive engineering software at university. Oftentimes it's a major PITA for everyone. The PhD students have to get their work done and are met by the software refusing to start because all licenses are taken. Sometimes someone forgot to log off or the computer crashed and the software takes most of the day to recover that license. Or some people do like 5 simulations in parallel. Or lock the computer, go home and block a license. The IT department will get lots of calls and have to deal with it. Especially when the pool of licenses is small. And it takes additinal effort to coordinate practical courses and excercises where you teach a group of 24 people which then need half the license pool available at a fixed time each week, despite the daily routine of everyone else.

And I'm not even sure if the people responsible, care too much for pirated software. But they're liable. Of course they write strongly worded mails when talking to everyone. It's their IT infrastructure and they can't have people do illegal things with it. Especially not while having an expensive contract with some supplyer. They can't have anyone leak a mail where they endorse piracy. Or post screenshots or turn in assignments or papers with screenshots that say "unregistered copy" in the bottom corner. And once students do silly things and the piracy is on display publicly, they'll have to do something. Usually that's writing a strongly worded email first. Because that takes next to no effort. I think the usual IT department doesn't care as long as things go smoothly, people do their various things and no one complains. They usually have other stuff to do. That makes me think in this story something must have happened that warranted some form of public reaction or at least show they addressed it and they have it in writing.

And I think the rest of the mail fits such IT people. They said why they do it and that they can't have piracy connected to the institutes name. They say they need some incoming complaints to justify buying more licenses. And the punishment fits the crime. They just disconnect the computer from their network and it's not their problem anymore. I think that's fair.
