Well that might be part of the strategy of no big announcement / celebration on the part of Iron Stone. Just quietly going ahead with your business, like its no big deal (which in theory it shouldn't be), doing what you can to improve relations with your nearest neighbors, ignore the self-appointed rabble rousers. Sounds like a sensible approach to me for someone who wants to be a long term positive presence in the neighborhood, not a constant lightning rod.
The other thing is probably even for many gentrification-fretters, the Bucks Hosiery fire is reminder that you can't leave these hulking old industrial sites unused and slowly falling apart forever. Its better to get these turned around and contributing to the neighborhood instead of being a drag on it.
Leaving that building empty is not helping anyone, giving anybody jobs.
