So that Gate that shall not be named thing has been putting together a list of sites and companies that they think ought to be boycotted. As part of the campaign they also tried to contact all the advertisers on one or more of those sites and try to convince them to cancel.

When the game industry news site Gamasutra published an article by Leigh Alexander, "'Gamers' don't have to be your audience. 'Gamers' are over", GamerHate added them to the list.

Unfortunately Intel decided to listen to them in this case and canceled the ad campaign deal they had with Gamasutra.

A couple days after that Intel "apologized", saying that it was not their intent to give the impression that they had chosen sides in the debate. However they did not un-cancel their ad campaign. So they're sorry they might have given the appearance of choosing sides, but they're going to continue on with having chosen a side.

I don't know if regular people writing in can undo the damage the Gaters did, but it's worth a shot.

And it should be noted that that Intel isn't the only company that they've had some (initial) success with.
