I love hearing furry youtubers talk about how great it is that staff and volunteers for cons do it for the love of the community, not for money.
I hate how my next thoughts are, "they're non-profits because online furries will treat it like a crime if they aren't", and "regrettably, not all staff are around for anything more than personal gain".

@david Hmm, for sure you're right there would be Discourse but I think it's telling that most of these cons were nonprofits before we were all too online. They're just easier to get started: tax reporting is simpler below some level of revenue, and it's illegal for corporations to have volunteer labor. (I know that doesn't mean it doesn't happen, but still ) Plus people are more likely to donate to get a nonprofit con off the ground than a for-profit one.
