You know who cares? The unions--the teacher's unions.
I am active in the teacher's union and I could tell you story upon story. The most egregious is that we had 2 state college (now universities) presidents who were found to plagiarize or even worse, just make up citations that didn't even exist. One claimed he wrote 50 articles; the union looked them up and they were not to be found.
You would think people smart enough to get into these places would be a little more strategic in their claims, but they're not. The union used it as a pressure tactic against the administration on various issues.
Did they have to resign? One eventually did, but I don't recall if it was strictly because of the plagiarism. The other one was in cahoots with a politician and was basically covering the area in asphalt at the bequest of the construction contractors. They were building buildings that couldn't even hope to fill with classes. Eventually that politician went by the wayside and the college president was gone for some other reason.
But the damage was done: To fill the slots, they started letting anybody in because they wanted the tuition $$. I left because I couldn't stand the quality of the students. It hurt financially, too. It was a good paying job and it took me a year to find something the equivalent.
Anyway, long story short: the people who care have an axe to grind. Regardless, it shouldn't be happening and says standards are not being adhered to. Scholars who are supposed to supervise this activity are not doing their jobs. I looked at their side-by-sides at this link, and it's way over the top:

Of course it is entirely possible this is made up BS, just like the impeachment hearings in the House.
