From the article:
> The real problem here is that there’s no way to know just how much of VPN traffic is growing or how much of it is BitTorrent.
That's a show-stopper problem for the entire article. All of the claims made in the article hinge on the idea that BitTorrent use is undergoing a "Long, Slow Decline". But the author provides no way to back up that claim and buries the lede suggesting why: they don't have the data to back up the claim in their chosen title. The article is largely a joke, a collection of baseless speculation, propaganda (including uncritical use of "piracy", "Legitimate Alternatives")[1], no awareness of why people share data via BitTorrent, and nothing that indicates an awareness of how laws differ around the world (an American bias is unacceptable since the Internet, BitTorrent use, and alleged activity are all global). Sadly some of the feedback on this group echoes the same sentiment: claims about what most people do without posting any sources to back up the claims.
On top of all that, the article is hosted on a service that could use a more resilient underlying infrastructure. As one poster here pointed out, it's as if the article should have been hosted on a service that lets people pass around verbatim copies of the article.
[1] See http://www.gnu.org/philosophy/words-to-avoid.html on how these and other terms are unwise to use without explaining what you mean. One of the giant risks is conveying an undisclosed viewpoint that colors your take on everything else: "unauthorized copying" or "prohibited copying" could have been used instead of "piracy", for example. I'd add "legitimate" to that list of words for the same reason: the word implies that such copying is illegitimate where it is illegal. But as that gnu.org article also points out, "[L]aws don't define right and wrong. Laws, at their best, attempt to implement justice. If the laws (the implementation) don't fit our ideas of right and wrong (the spec), the laws are what should change.". If we're to have a reasonable discussion of this, we ought to admit to our views and speak of them clearly, not hide behind propaganda without ever explicitly coming to terms with their implications.
