'not for profit' don´t means don´t charing money, it means that money don´t goes to founders/owners

maybe the sponsored money goes to pay the rent, beers and food so the event can be free, and any money goes to founders/owners

[analog]

Not for profit means the organisation doesn't distribute funds to shareholders. The founders/owners are still free to pay themselves a wage.

That's what I mean about 'sounds nice and fluffy', actually it means very little in practice.
