Unpopular take: ProctorU is trying to solve an unsolvable problem. The only way they can make it work is by dictating the configuration of the device taking the test, and even then they are going to have lots of technical problems with false positives and incompatible software. This leads to impractical outcomes like, "Oh, just borrow your friend's computer" and unsafe situations like, "oh, just allow us to scan your computer for content we don't like" and so on.
This is the digital equivalent of forcing students to be naked to take a test in person.
Impossible requirements have been placed on at-home exams and proctored testing; and this company stood up.
Are they violating many moral and reasonable privacy codes to do it? Absolutely. It is a huge breech of ethics.
But universities and their professors asked for it.
Plenty of online educators already know how to (edit: lead) classes and give tests without it; but many, too, are either lazy or overburdened and have asked for this.
