You can still pay for it by donating after the fact.
That's what I do.
Jb is not a business and never was for real jb devs.
It's not about the money.
And if you didn't get scammed there's plenty of scam websites out there that trick many people thinking they can pay to have something faster that is not even available.
Just thinking that you can have immediate updated iOS jb's is not really logical.
Jb takes lots and lots of work, time and most of the time team efforts by many. You don't just go up against the latest iOS version and a few minutes later you jb it immediately realistically speaking.
If it was monetized (like everything else in life) service would be faster. And it could be a business. In fact people advertise and jailbreak devices for people locally, so that portion of things is a business. As is Cydia and the apps,themes,etc. which are all businesses. Without them, jailbreaking would be pretty much pointless (for most people).
I think the only reason why the majority of the jailbreakers aren't making money off of their talent is that they are excellent hackers, with amazing computer skills, but lack the ability to monetize things properly (business sense). Because if they could make lots of money doing what they love, they would.
And I wasn't really meaning instant jailbreaks, but if there were was more competition, money involved, etc. there may be more interest/time spent on working on jailbreaking each subsequent update that Apple puts out.
