At first this article reads like your typical anti-piracy screed. It rants about how 10x more people watched GoT illegally (confusing them with lost sales) and ends with how downloading movies can get your credit card stolen.
The middle of the article however, destroys the author's case.
Time Warner (owning company of HBO) CEO Alan Bewkes stated in 2013 how becoming the most illegally streamed show in history was “better than an Emmy” and that torrenting ultimately led to more paid subscriptions.
“We’ve been dealing with this for 20, 30 years—people sharing subs, running wires down the backs of apartment buildings. Our experience is that it leads to more paying subs. I think you’re right that Game of Thrones is the most pirated show in the world and that’s better than an Emmy.”
The CEO of Time Warner, who knows more about the finances of his own show than ForeverGeek writer Tom Llewellyn, championed piracy and said that it brought them more subscribers rather than nearly destroying the show as the article claims.
Needless to say, Tom forwent a rebuttal in favor of writing how you can get malware from downloading it...
Anti-Piracy Propaganda: 0

They fail to mention that when GoT started in 2011, HBO wasn't available at all without a cable TV subscription, so people who had already dropped cable didn't have any other choice. HBO streaming without cable didn't become available until 2015.
Yeah, I don't think I'm all that special and I pirated the earlier seasons of GoT. The later seasons I watched legally, because by then it was available on a local streaming site I could well afford. If pirating wasn't an option it wouldn't have meant I would've spent the money to subscribe to a cable package that included HBO, (which would've cost a lot because you had to get some expensive bundle) I just wouldn't have watched GoT at all. So they didn't really lose anything from it.
And it's possible I may not have watched the later seasons legally either, because "eh... too late to get into this thing now."
HBO is a luxury thing and something like GoT could be the thing that'll entice people that could afford it and were thinking of getting it anyway to subscribe. The most relevant thing that influences their subscription numbers is the average income of the middle class, not piracy.
Most likely the entire HBO streaming service wouldn't have taken off, because they offered little to no avenues to consume their content to an increasingly no-cable subscription generation. It's entirely likely that HBO would've died out along with traditional TV.
