Because not everyone who reads the comics watches the movies breh. How many people on this board love saying they don't read comics? Or that they stopped reading comics when they were younger? There are much much more people who watch the movies than watch comics and that's an issue you can address simply by revealing the guy who runs the bugle is obsessed which is the same reason in the comics. You never question it in the comics because you know the man in charge has a vendetta with spider-man; it's a very personal thing between the two of them so of course he's going to cover him non stop in order to prove that he's a crook just like everyone else that wears a mask. JJJ would have no problem with Tony because he's a billionaire, he'd have no problem with cap because he's a war hero and Jonah respects that, and I'm willing to bet he wouldn't have a problem with the avengers as a whole although he would have something to say about the damage done to new york city; but this punk kid in a mask doing a job no one asked him to do? Yeah that's a problem.
And my point is, if its that easy for anyone who reads the comic to see it wont be that hard to portray it in the movies. Thats why that complaint should be dismissed.
