Bahaha... excellent points.
To play devil's advocate (former journalist here):
Journalists are supposed to just cover the events, not get involved and certainly not influence them. So they're really limited to just covering the public hearing. If they go beyond the public hearing to try to find residents who are opposed and interview them, for this story about the public hearing, then that would be getting involved in an unfair way.
The best a journalist can do is a separate, man-on-the-street type story to try to show what the general public at large actually thinks - but this is the absolute laziest form of journalism and it's used very sparingly and, even then, generally only for a fluff things.
A larger media company, like CBC, could do a proper poll - but that is hugely expensive and such an expenditure would never be approved for every little development, especially when there's only 6 people, all opposed, showing up to the meetings.
The only way to solve this is to show up. If you're there, if you speak for the development, the stories will reflect that side of the equation too. But that's our responsibility.
