Where did you hear that?

Amazon Web Services does not ban BitTorrent or IRC. They actually support BT as an official delivery method from S3.

I was referring to the passage in the article which reads (emphasis mine): 'Distributes, shares, or facilitates the distribution of unauthorized data, malware, viruses, Trojan horses, spyware, worms, or other malicious or harmful code (collectively, “Harmful Components”).'

I took that to include copyrighted data, including Battlestar Galactica episodes.

Yes, but what does that have to do with prohibiting BitTorrent and IRC?

Obviously a-priori is obliquely making the point that BitTorrent is mostly used for copyright infringement.
