This post is pish man, and if you want a reason, I'll give it to you.
You list a bundle of questionable decisions (none for us tbf, cause that's never happened and certainly at least two on your list were actually correct) where you are positing that VAR would have swept in to overturn them, then correctly point out a ridiculous decision from this season which didn't get overturned. Do you not see the problem there?
If there's bias and corruption - there isn't, it's just bad decisions - VAR would be a tool to further it, not end it.
