Re: difference here is that they offered it free
No they didn't, they just included it in the price of attending the convention. Although I'll grant most people don't quite see the difference.
Depending on the location and the terms of the rental contracts, the use of personal wifi can be excluded in meeting locations. And you're right, money is always a part of it. It's just a question of whether or not the payment is reasonable given the circumstances.
