So Who's a shill?

So what motivates the anti-development forces? Many seem to think that people who promote new development are “shills” for big developers. In that vein are anti-development folks shills for large Manhattan landlords? Are they just fronts for rental apartment owners who don’t like the fact that Brooklyn is siphoning off people who otherwise would have been competing to live in NYC apartments? Are they shills intent upon helping Manhattan landlords drive apartment prices up and vacancies down? Yeah, that’s the ticket, anti-development folks don’t believe a word they say; they’re just shills for Manhattan landlords.
