Probably not. The Networks had ways of ignoring the public back when all you could do was write a letter or call their switchboard. Mass complaints rarely worked (Star Trek is an exception). I suspect that today they have measures in place, which are more in keeping with modern communications. Decisions about which shows to zap, regardless of the ratings, are made by a bunch of nameless, faceless poobahs, aka "Them", who sit in offices and run things. How much we miss our fav shows, and the stars that become almost like family, matters not one whit to them.
