That's a common story; in my university (in Padova, UniPD) happened something even worse. They tried hard to shut down an unofficial app (Uniweb) that was installed by most of the students in favor of the "official" one, that was completely unusable (and probably was born out of a rigged contract). At the end the best one won and became official, but that was after a lot of struggle.
Sounds like what happened with the Apollo app and Reddit
Reverse engineered just enough of that .net monstrosity to get the data I cared about. Replacing the school's portal with my own script made me so happy. They kept breaking my scraper constantly though, got to the point it was too much effort to maintain it. Worst part is I don't even think they were doing it on purpose. They were just bad in general and couldn't keep their site together.
Having said that, speaking as a Macalester alumnus, I wouldn’t put it past them to be a bit petty behind the scenes :)
