Dead_Metal, you can still criticize people. Just look at half the world criticizing politcal leaders, etc.
And I am not "against keeping XMP alive". I am against pissing off Atari so taht they won't "push the button" as you stated (I am pretty sure that keeping a master server up takes a bit more work than that).
And you say they need the community? That is the point I have been trying to get across the entire time. You have one dying community, and one community that is just starting to come back to life. What would you do? I sure as hell know that I would nurture the strong community. And rather than divide their fanbase (and cut down on possible UT2k5 profits), they can group them all.
I am against the killing of XMP, but I also understand why they are doing this. It is simple business. U2 is a failure in their eyes, so they are trying to do things "right" with UT2k4. It is not a great thing, but all you are going to accomplish by flooding their forums or inboxes is to annoy them even more.
If you perhaps organized a petition or something, THEN they might take notice. But let's face it. Most of us would just send hate mail after hate mail. I know I wouldn't, and I doubt the topic creator would either. But just look at the majority of people online, they are dumbasses. And I sure as hell know that in a situation like this (where killing XMP outright will earn them more cash), the impression we leave is very important.
If they were considering an attempt to kill XMP, and ther was not something like ONS, then yes. I would join in with all of this harrassment (just look at how I have treated Akiva Goldsman since I found out that he was butchering Asimov's masterpiece). But right now an orderly and supportive community is more important. You want them to think "Well, I suppose we can let them keep this. Maybe they can save XMP" rather than "Dear god those guys are morons, kill it now so that we don't have to worry about it later."
