This is not what they're describing. Have you ever gone through the process of receiving an accommodation at a university? It is significantly more challenging than just having a diagnosis. They will look for every single possible excuse to refuse you access. They will require you to repeatedly book new doctor's appointments to get extremely specific wording for any accommodation you may need. Your doctor will have to fill out multiple forms for the university. Then, for each class, you will have to meet with every professor you have to request your accommodations. Many of these professors will try to talk you out of using them, or find ways to get around them.
