World Just why DOES Daily Bugle publisher J.Jonah Jameson hate Spider-Man?

This is one of the enduring mysteries of the Marvel universe( kind of like never seeing Dr Doom or The Red Skull's faces).
Moral disapproval of "vigilanteism," the official pretext for Jameson's animus towards the web slinger, cannot be the reason, since Jameson knows that Spider-Man, unlike say the Punisher does not kill criminals, and there are other heroes similar to Spidey who are never the target of the Bugle's wrath(Moon Knight, Daredevil). Singificantly ,even the Punisher who is known to kill, is rarely the target of the Bugle either.
if we rule out the improbable, as Sherlock Holmes, put it to Dr Watson, then whatever remains, no matter improbable is the truth.

The kindest thing I can say about J. Jonah Jameson's obsessive hostility towards Spider-Man is that is seems not to be rooted in any anti-mutant prejudice( WE know that Spidey isn't a mutant but the general public of the Marvel Universe-especially the average New Yorker-doesn't); Jameson displays no especial animosity to the X-Men (or even the Fantastic Four or Avengers-indeed he is known to be a fan of one particular Avenger, Captain America in particular) beyond a moral disapproval of "super-heroes"

A cynic would say that going after Spider-Man sells newspapers and nobody with the exception of Aunt May Parker, seems to have cancelled their subscriptions due to the Bugle's anti- wallcrawler crusade!

It may be a combination of motivations-simple jealousy of his Spidey's moral qualities, a desire to sell newspapers and suspicion of masked men( this is unlikely as Jameson KNOWS that the wall crawler unlike Wolverine, Venom or the Punisher is no killer)
