Some people get it in their heads that they're somehow entitled to watch "Game of Thrones." If the distributors only make it available on one platform, one that you don't want to use, that's their purview.
Nobody has the right to watch "Game of Thrones," and not being able to find it on a platform you prefer to use is not a valid excuse to steal it.
The item used as an example (I Tried To Watch the Game of Thrones and This is What Happened) is about how none of the sources/distributors were making it available even when the person was ready, willing and able to pay for it. (And from the context of the pictures he would have been content to do streaming or DVD/BluRay Disc — he wanted to buy the show itself, not have to but a subscription to HBO [and get cable, too]; so I don't think it's quite fair to say that the platform was the issue.)
I'm not saying that stealing is ok, but it's a good illustration of how easy it is for a company/producer to shoot themselves in the foot with DRM (or, more generally, by making it impossible to legitimately get ahold of the desired product).
