CCC would be better but REcon is kind of niche because it’s focus is reverse engineering and not “hacking”in general.
I wouldn't call it crazy that a pure volunteer event that constantly has to switch places because they use up ALL available space of their venues does have a ticketing system that is still better than the one of a lot of big pop stars.
It probably also keeps commercialization down to a minimum.
Yes, sucks that what you describe isn't possible, but I think in perspective it's not exactly "crazy".
It's still always sold out with whole conference areas and more used up.
