It wasn’t a new article in their KnowledgeBase, it was an update of a much older preexisting article. They only bumped the version numbers of the recommended software.

After all the flak from folks who’d never noticed the article was there until the update, Apple in response took the article down with the comment that most users really don’t need AV software, because Mac OS X is inherently more secure than something like Windows.

In conclusion, this was not Apple capitulating on the claim of OS X’s security, and the net result is they actually said it’s more secure than ever before.
