He does not mean it as a comment towards archive.org, he means information in general. With increasing threats to free speech and censorship, he suggests that the information that's not popular - or, censored/manipulated/bubbled by mass media/governments/etc. - can only survive through decentralized means of storage and distribution, like BitTorrent.
In essence, he argues that BitTorrent can be a fantastic way of digital preservation, which is the goal of archive.org, and I suspect he uses the word 'pirated' interchangeably with 'torrented', since that's what BitTorrent is commonly associated with.
