No. I will do what I want when I want. I will not miss out on great games, movies or songs for some protest that will end up doing nothing. If the movement gets big enough, and is actually carried out by all those people (I'm talking tens of millions here), then I'll join in. Until there is a sign this is working/will work, I'm not hurting myself for no reason.
Now, there will be few things I consider worth buying anyway, so I'll be semi participating by default, but I WILL be getting Mass Effect 3, and anything else that catches my fancy as the month goes on.
