So if I'm hungry and I walk into a McDonald's and as you, Jynnan, to give me a 99 cent cheeseburger, but I can't afford it ... in your definition, I can accuse you and McDonald's of being exclusive? You may argue the definition of exclusive and the use of semantics all you want, but there has to be a bit of logic in an argument for it to be valid.
The basic definition is: not divided or shared with others. The Fan Faire was very much divided and shared with others. They extended an invitation for everyone to come, if they could. That is NOT exclusive. As someone else mentioned, it would have been exclusive if they said "For US residents only, don't even think of coming if you don't live here because we won't let you in." That would state that even IF you had the means to go, you still couldn't and THAT is the definition of exlusivity.
The bouncers who don't let people into clubs because they didn't dress nice ... not because they COULDN'T dress nice, but because they DIDN'T dress nice. That's exclusivity. If they dressed nice and came back, they'd be allowed in. That's NOT the same as them saying "Hey, come to our club, everyone's invited" and you saying "Bah, you're being exclusive because I have to spend money on gas to get to the club." It's childish and you're whining because they set something up (perhaps over and over) where you couldn't get to because of YOUR own finance issues.
However, as I said before, the contests that are US only are exclusive, and for good reason.
