1) Today's umpires are objectively better, albeit still not good enough.
2) Asking to use available technology to improve the fairness of the game and the adherence to its governing rules is "complaining"? Ok.
The area around the 9 quadrants is the leeway area. Pitch/FX also shows the corners of the strike zone "grayed out", and that's to signify the gray area around the strike zone.
That's cognitive bias, for one, and made-up hoopla, for two. I watch a ton of MLB games and don't post my thoughts on all of them. How can you know what I'm thinking?
1) No, it would be enforcement of rules that have been in place since the middle of the 20th century.
2) The umps' union is weaksauce.
3) Umps suck because they have an impossible task, we have the technology to help them. The issue is reaching cinder status.
