That's run and operated by a private company, Delaware North. They have to get NASA's permission to operate, of course, but they're the ones raking in the profits. NASA's happy about it because they no longer have to pay a dime to maintain the visitor complex, it used to be a money hole.

NASA generally doesn't make money through irrational fear mongering. Generally. There are exceptions that piss me off, so I'm an equal opportunity critic.

Honestly I'd just get the info out there, I wouldn't try to make money off of it. Maybe that makes me an idiot. Honestly I AM an idiot, in a way, for not using my talents to perpetrate a hoax that could actually look credible to those who don't know better or have a way to check for themselves. I could put hoaxers like the "skyview team" to shame if I really wanted to, and probably make money off of it. Money is not the reason I disbelieve Moore, however.
