There would be less incentive toward this kind of piracy if content producers and distributors could get their collective acts together with more liberal licensing. Popcorn Time is winning because it's easier to use and find content than any pay service. Like anything, you compete by making a better product/service -- not by complaining that your competitors are unfair. Of course, they are certainly unfair here, but…
I call bullshit. Absolute bullshit. If I gave you a credit card that gave you unlimited access to digital content you probably wouldn't be complaining. Certainly not if you live in the US or much of Europe. If you have a $69 AppleTV then iTunes is a spectacular user experience. Search for almost anything you want and hit play. If it didn't cost $5 to rent a movie it's superior to torrents. This is where someone chime…
For instance, I have a season pass to Mad Men right now, which airs on sunday nights. I don't get the iTunes release until midnight, so I end up not watching it until Monday (even though I pay for it!). If I used torrents, I could watch it Sunday night with everyone else. Other shows have it far worse!
New movies usually enter the iTunes market in a buy-only mode for the first month after release. I'm more than happy to pay $5 to rent a movie, but I'm not spending $20 to buy it. So I wait weeks or more after release of a new movie before I can rent it online. If I used torrents I'd probably be able to watch it for free weeks before release.
iTunes has a good catalog (so does Amazon, and others I'm sure), but movies/TV are not the same as music on iTunes and still have farther to go before they're truly competitive with piracy in terms of user experience.
