I said this two years ago:
It's nothing to do with their fitness: the issue is that they're a closed shop who are regulated by the PGMOL - all ex-referees - so they look after themselves.
There is no accountability: if there are errors and mistakes then the lengths they go to defend them with questionable outcomes, if there are any, is ridiculous.
Before that, I said something similar and again something similar before that. If they make a mistake, which they often do, you
may get an apology, but it's glib.
There's no real reflection nor is there any retrospective action against either the referee or changes to the system . The same ol' ineptitude goes on and on.
As others have said, I'd go back to the days of VAR at the drop of a hat as I could 'accept' errors made in the here and now, but VAR is farcical.
The fun of the game is being sucked out of it, and you rarely have a day of fixtures without something contentious, at a minimum.
