Because Sidewalk has avoided answering those questions. If you go to the meeting all they will say is that "we don't know" The meetings have been a giant waste of time.
Have you actually been to a meeting and attempted to ask questions? Or are you just repeating the same hearsay as the guy in the article is?
I went to the first meeting and felt they did a pretty good job responding to concerns. There were some protesters outside before the event, expressing concerns about affordable housing, but by the end of the meeting, after a bit of back-and-forth in the Q&A, it looked like even they felt they were being taken seriously.
I have attended the meetings yes. We no nothing more than we did when this was first announced.
