The price of everything on recreation.gov is already so cheap, honestly I don't care about their fees. It's like, ten bucks in fees for staying a night somewhere in the San Francisco area. Far, far lower than Airbnb fees.

The problem that most bugs me is how often reservations for popular campsites fill up the moment they become available. And then when you go camping, there are often empty sites. It's so cheap to reserve campsites, and you have to do it so far in advance, people reserve campsites they aren't sure they want, cancel their plans later, and don't even bother to inform the campgrounds.
