Perhaps the "war" part is overstated. There is such a thing as a company not wanting to expending resources to support the position taken by any conflicting parties, at least not, until there is clarity about how conflict will resolve. Why alienate any customers, by tying your name to one position or the other?

Companies routinely stop ad campaigns, if there are complaints. Perhaps Intel isn't taking a position at all, and they are merely reacting to a flood of supposed complaints, in order to help protect their brand.

The original article contains has a certain view of "gamer culture", and people might find a number of the statements they could have claimed as offensive.

So maybe Intel knows or doesn't know about the GamerGate campaign... maybe it is or is not related to the early end of the campaign

I would just rather believe all this can be easily ascribed to stupidity, so there is no reason to assume Intel's termination of the campaign is a malicious act, or taking one position or another with regards to the article.
