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).
I'm not judging people by stating that certain strategies don't work.
It would be judge-y if I stated that they were stupid for believing such a thing. Which was not my intention at all.
Not buying a game is by definition inaction. It's not the fault of the people that this is the only way left for them to "protest". But as I said: it's also not a moral imperative to do anything, if you're not able to.
