I'm 100% on board for any boycott. We'll cross this bridge with Sony as well if they go down this road.
Microsoft has now come out in the open and stood behind what we all feared. There's no confusion left but in the tiniest nuances of this story: they are gunning for us as consumers, and it's either we stop it now or this industry radically changes into something not worth saving (if it even survives at all anyway).
If this not worth a boycott, absolutely no bit of game news would ever warrant such. If this is not worth a boycott, then we might as well all just go home and allow any business to take advantage of us simply because we don't want to put in the effort to push back. If this is not worth a boycott, then we never really loved games in the first place and this hobby of ours needs to go down in flames anyway.
I say, if this is not worth a boycott, then nothing in this industry ever would be.
