Well, isn't that what we're doing here? The entire point is to communicate you stance to others.

What you're doing here is not a coordinated effort.

And there's quite a few AAA titles that have suffered simply because the customer base actually can communicate.

Lol. Whut? I can point to no example like that and ample examples where these kinds of "boycots" did squat (like e.g. with the original Modern Warfare 2 not having a server browser).
