Exactly, especially when the shows creator tried to make it for as large an audience as she could age-range wise.
As is pretty much their jobs in hardly different than any other show producer.... And it's not like she did it for a "I want 20-year-old men without kids to watch this" sort of way but more in a "I want fathers to be able to sit down and watch this with their kids, as good parents should, and not wish death upon themselves."
It's the same reason the Disney/Pixar movies have stuff in them for adults to like, so the adults get some entertainment out of it all too.
I doubt Miss PonyMaster intended for single, childless, 25-year-old men to be raving, drooling, lunatics over this show.
Some Bronies treat the woman as if she is great Messiah of cartoon tv! A wondrous woman full of gold, love and heart who made awesome.
She's not.
She's a TV-show creator deemed with the task of making a show to appeal to as wide of an audience as possible in order to generate high-level of ad revenue and move toys. That she was, somehow, able to make men out their willingly fall in love with a show about freakin' cartoon pastel-colored
ponies is just a bonus.
