A good developer will separate wheat from chaff. What anyone says here can be either, and given that a developer is not obligated to follow anything we say at all, I see no harm at all in insisting that the developer is incorrect so long as it does not edge on harassment. Opinions are opinions-- nothing more, and it is up to the developer whether he is convinced or not. An unsupported dissenting opinion ought to be attacked for being unsupported, not because it has crossed some arbitrary line of courtesy. Again, absolutely no one benefits from complacency, on any grounds. Not the developer, not the dissenter, and not the people opposing the dissenter.
I don't want to talk about Mass Effect 3 too much, but I will say this: I don't know what the hubbub is about, but if the devs are changing something, then they are doing it because it is in their best interest to do so. That ending was five kinds of putrid ***, left to ferment in a covered jar with the corpse of Bioware's creative dignity, and if they decided to do anything to it-- anything at all, then that is THEIR decision. The buck stops with them-- just as we cannot force Alex to make changes that we may want, so too is it impossible to blame 'gamer entitlement' for what may have happened in regards to Mass Effect 3. The final line of responsibility works both ways, and if one claims to respect their creative integrity for whatever they originally put out then one must also respect their creative integrity in anything they may do afterward. You cannot have it both ways.
