Thanks for your feedback. I will say this and I will end my part of the discussion.
Firstly, I guess if anyone has more of a right to complain about not getting fair treatment from other countries it's the U.S plain and simple. As I've mentioned and you've been conveniently ignoring it, the U.S. gets very little access to much of the great tech that resides outside the U.S.
You'll just have to accept it, this is not something to complain about it. It's a World Wide Developer Conference and if anyone stands to make money from attending then flying from outside the U.S to California is more than convenient and cost worthy. If developers outside the U.S think that's too much for them to handle then they either don't have the funds or the time or are not taking their business seriously. That's on them. You're only looking at this from a customer standpoint rather than a business one. Of all the things I've heard developers complaining about, your complaint isn't one of them. Small garage entrepreneurs have many hundreds of thousands from the iOS store.
What is a plane ticket from outside the U.S. to California, $2000-5000 at the most? Plus the WWDC ticket and hotel. Under $10k for a developer that stands to make more than 10X that amount.
BTW, are you a developer which is why you even brought this up? Just curious.
