For clarity, I'm totally for this suit, and hope that the public can claw back those dollars.
But in the grand scheme of things, that seems like such a minor technicality. $6 to $15 here or there, a couple times a year on vacation, is way better than the alternative systems that were common before recreation.gov, with faxed lotteries, long delays, and high uncertainty. It used to be common that you'd just have to drive to the place, wait an hour or two in line, pay the admission fee (if you don't have a annual pass), then sign up for some lottery on the spot at like 7am and wait a few hours to hear back. If you don't get it, well, there goes your plans... but you're already there.
By contrast, a small fee here and there for the ahead-of-time guarantee of a reservation is totally worth it. $130,000 to run a lottery system effectively? That's not a whole lot. Even if it costs a few million, nationally, to run them... that's nothing. I can pretty much guarantee you the NPS, USFS, and BLM together wouldn't be able to run a smooth national reservation & lottery system with the same budget and fees. The agencies themselves are so far removed -- in both mission and skill set -- from modern app UX that they probably wouldn't be able to get the job done even with 10x the budget.
I don't doubt that the contractor (Booz Allen Hamilton) is a scumbag for pocketing those fees, which are unnecessary to begin with (it's not like it costs $15 in CPU or human processing time to do a change). It'd be great if the public gets those back.
All I'm saying is that recreation.gov is totally and absolutely worth it despite these fees, despite the increased costs to the public, because it actually works, vs the chaos that came before it. That website makes public lands FAR more discoverable, accessible, and reliable -- at the cost of minor corruption. I think that is an ultimately acceptable tradeoff, even if it's not ideal. (And it's not like I'm some libertarian; I love our parks and public lands, but digital anything just really isn't their strong suit. I'm grateful they outsourced it.)
Maybe what we need, in lieu of effective federal digital agencies, is some sort of public-FOSS partnership that can take the place of public-private partnerships. But that's much harder for the agencies to deal with than a central commercial entity with designated contacts, support, etc. And the FOSS model isn't really set up to communicate in the real world with the super complicated division of public lands across federal/state/local/agency divides, each with their own little fiefdoms and idiosyncrasies and rules and regulations.
I wonder how other countries manage similar use cases (digital presence for public lands)? Recently went hiking in Taiwan and reserved a trail permit; the UX was terrible even by 90s standards -- at least it was online -- but at least it worked. Not sure how they funded it, but I don't remember there being any fees.
