The underlying context is that I was practically a persona non grata. Teachers would happily leave the class to me during labs but hated the fact I barely attended. I'm talking not even grading your exam sheet, or putting an arbitrary grade, and not displaying it until the recourse deadline has passed because "screw you" and I'm talking putting "0" on all your grades because you missed one exam. Nobody will take the side of a student who'll be there for a limited time against a colleague they've worked with for 20+ years. Even if the behavior is unjust, the rationale for them is that you'll live and learn and forget about it and leave, but they're staying and have to work with the other person.
Sure, the obvious step is to go manoeuver or call out these practices, invovle lawyers, and the media, and what not. Which brings me to my first paragraph. What is obvious and possible somewhere isn't somewhere else, or is but the stakes are too high. If I wanted to manoeuver in a cesspool, I would have become a politician. If I wanted to go to war, I would have become a martyr. The former is frowned upon, the latter is admired in other people from a distance.
Their red tape is only your problem if you can't self-help. It's not your job to enforce their agreements with third parties who aren't you. It's also not your job to inform them of existing agreements with third parties which you are privy to.
