Signalling in Bitcoin is nothing more than a bunch of big shots barking to 'prove' a point, where in case of Bitcoin they have no other option than to follow and go with what's better for the protocol. Miners aren't totally stupid, they only care about the price to sky rocket and have their mining rewards be as valuable as possible, and looking back, the price did sky rocket. Miners should be respectful and thoughtful, because they are the ones with millions and millions in hardware running all day long -- messing up Bitcoin means messing up their operational results and that's not something they will allow to happen....
