Miroslav has a point. The Wordpress foundation clearly does not WANT other Wordcamps to be on anything near the scale of the original. It would diminish the status of Matt's own conference. Obviously that's why Jane wanted to change the name of Wordcamp SF -- so people wouldn't complain about it being a special case.

There is nothing to stop people organising large-scale conferences elsewhere, but in order to be successful they are going to have to do it outside the aegis of Wordcamp. I don't quite know where people get the idea that the Foundation is in any way accountable to the community. It's not a democratic or representative organisation, just the means by which Matt protects his assets and redistributes some of the largesse to arbitrarily selected beneficiaries. It's designed to protect Matt's interests, not yours. If you want fairness and accountability, you're going to have to establish your own foundation based on those principles.
