No they don't. They make it very clear that this was done by exploiting a flaw in Java. > The same software, which infected Macs by exploiting a flaw in a version of Oracle Corp's Java software used as a plug-in on Web browsers, was used to launch attacks against Facebook, which the social network disclosed on Friday. That being said, even if it is Oracle's "fault", most malware works by exploiting third-party software such as Java or Flash or Acrobat - including most Windows malware. OS X may be "becoming less secure", even though OS X itself hasn't changed, due to the fact that some Java and other exploits are now being used to target OS X machines. This is all covered very fairly in the article.
