after St. Louis police unions instructed officers to publicly display The Punisher's insignia (the mark of a lawless, fascist murderer) the comic book community was quick to point out the stupidity, and the frankly horrifying message sent by supposed peace officers endorsing a maniac. So it's a good thing The Punisher personally confirms he hates cops who see him as a friend… making every cop who "wears his mark" or calls themselves a "fan" look like shameful fool in the process.

I mean, isn't that literally why he tells people to not be like him?
I think he was created to point at that exact issue.
I think it highlights the difficulty of attempting to profit from attempting to satire fascism. The people who understand nuance aren't typically the crowd that needs to be reminded that fascism is bad, and the people who do need that reminder are so often selectively deaf to nuance that conflict with their ideology.
Punisher may have started as satire on fascism, but over the years there are going to be authors who are going to asses the importance of that aspect of the character differently. Some are going to take the original message to heart and make it the centerpiece of the story, others are just going to use it as a set piece to get to the vengeance and violence.
Over time the character turns from the cautionary tale of an antihero, to a piece of intellectual property used to sell stickers to chuds. Unfortunately the author has very little control of how people interpret their work.
