It's not the institution giving the test. It's a for-profit corporation that has a de facto monopoly on standardized testing in the US. It's also a company who has been slow to modernize their test (both content, scoring, and process) and has slowly lost the faith of many colleges/unis. And the students are paying for the "privilege" because their test is the gateway to higher ed.

The at-home test format is new. It's usually given in a test center (either private or at the secondary school) with a proctor. Students usually prep for years for this exam, but all that prep would be for the on-site proctored exam. This was new for everybody, and appears to be poorly executed by the company that profits handsomely from these exams.

Based on the article linked, the message went out the day of the exam, after some students were already mid-test. That's not helpful.
