The assertions in the article are not "speculative horseshit". In 2011, Netflix+Youtube+BitTorrent alone were over 50% of internet traffic [1], and all three have likely grown since then. The NSA has no interest in the vast majority of this traffic.

The exact numbers are speculative because nobody has data accurate enough to determine them with any real certainty, but the point is that the NSA is misleading the public about the extent of its surveilance by orders of magnitude.
