The article didn't just talk about the Saudi attack. It gave an overview of the history of similar attacks. Stuxnet was arguably the most significant of those, and it's especially relevant since they're blaming Iran for this attack.
Personally, I don't want Iran to develop its nuclear progam; however, there are legitimate concerns that such cyber attacks set precedent, or even could expose security flaws, that might instigate retaliatory attacks towards the US and its allies.
