Agreed. Which is one of the biggest—and longest running—frustrations of fans that the powers that be continually to either ignore or actually make worse.
And the lack of accountability for (often continually) misapplying what laws there are that seem to actually be straightforward is another source of grievance.
I think we all agree with
@LangleyBlue1970 that referees are humans and are going to make mistakes (and unfortunately come with inherent biases of different kinds, as we all do), so we cannot expect them to be perfect, in any match, much less every one of them.
But I do think there are some that consistently make the same bad calls from match to match (or all referees that make the same poor decisions across the length of the season), whether due to confusion, incompetence, or prejudice (or all three), which are not actually addressed in any real way.
We’ve all highlighted the possible structural reasons for the lack of real accountability (not enough referees, inadequate training, poor support mechanisms, woeful design and implementation of VAR, etc.) but all of those issues have remedies and, by and large, the league and PGMOL don’t appear to be overly committed to exploring solutions for them. Or they drag their feet on solutions, like semi-automated offside or broadcast official in-match communications (which would help to humanise referees).
I think the offside yesterday highlights that more than anything. Everyone involved—officials, players, managers, commentators, pundits—didn’t like how it played out. Literally no one was happy with it. I would wager the assistant referee desperate to raise his flag was the least happy out of everyone. But the actual decision makers that can help avoid stop this situation from continually occurring don’t seem particularly interested in doing that.
And that is a legitimate source of frustration.
