Recently Activision / Infinity Ward have announced that there will be no dedicated servers (which means no mods or clan servers) for Call of Duty 6: Modern Warfare 2.
There is a growing community of PC gamers who are encouraging a boycott of the latest Call of Duty game for PC. Below are just a few screenshots from the in game browser of Activision's latest CoD game, Call of Duty: World at War.
A rough calculation shows that about 3-5 % of all the CoDWaW servers have the word boycott in their server name. Undoubtedly, more are encouraging boycott by other means.
