Your interpretation sounds excessively jaded to me and irreconcilable with the communities I know that continue to nurture and grow from BM.
I notice in particular your comment about coming to catered camps. That's precisely what Burning Man's community is pushing back hardest against, because the community wants to avoid the exact degeneration into vapid entertainment that you're claiming it's become. It's deeply deceptive to suggest this is a lost battle, or that the heart that makes this community something more isn't still strong and fighting very hard for the good fight.
Edit: I didn't notice your comment about gay people. What are you trying to express there? Black Rock City has to be one of the most gay-friendly places on earth. Where are you getting these ideas?
