The way I am taking this is:

Pantheon decide to advertise through the venue instead of through WordCamp.

Matt Mullenweg got upset because Pantheon didn't go through Matt Mullenweg's route to advertise. Even though Pantheon can do that.

I see no problem of any company advertising directly at the venue that an event is going to be held at, as well as the event itself. Double advertising.

I think Matt got upset that he/WordCamp US/WordCamp Central/WPFoundation, etc...didn't get that Pantheon's money.

Matt talks all the time about the community but situations like this makes it look like it is his way or no way. I don't like this.

I have volunteered at WordCamps, I have attended WordCamps, Companies I worked at have donated to WordCamps, I have paid for people who can't afford to attend to attend.

This whole thing makes my stomach feel queezy.

If WordPress and related companies/products/events then Matt Mullenweg should not be the final say. It should be a Council, Board of Directors, or even have a vote on things.

I honestly think the WordCamp rules should be put up for a vote by the community.

Obviously I am going to say, harassement, abuse and so forth shouldn't be allowed.
