I'm not sure what all the public complaining about officiating accomplishes, or what the end goal is.
Despite all the mistakes, these are humans at the end of the day. Just like a human athlete is going to line up offsides inexplicably, or jump the snap on 4th and 13 inexplicably, sometimes a human official (who is making significantly less than those athletes) will miss a blatant pass interference, or err on the side of not throwing an intentional grounding penalty that should be called. It's all a part of the game.
There are arguments to be made that at least some contingent of the officials should be full-time year-round NFL employees... But I have a hard time believing these aren't the best individuals in the world at what they do. Those with a long-term memory still have nightmares from how badly their replacements stunk up the joint ten years ago or so.... It's just a really hard job, and I don't think Patrick Mahomes acting like a toddler on the sideline after a clearly correct call helps make it any easier.
