i was always skeptical on people saying that torrentz are a symptom of bad legal streaming services.. Well, i recently got myself a videoprojector with an android tv included, and since i happen to have an amazon prime account, i installed the app, which is quite good. And yes, it's true, since i've done that, my torrentz usage has dramatically dropped..
I agree. It seems like an flippant opinion, and I'm sure many use it that way, but some services, and frankly, regimes have proven that convenience, comfort and ease of access is very attractive to people. If a service can navigate the obstacles such as copyright, they will be more popular than taking the thing for free with a bit of work.
Ease of use and guaranteed video & subtitles quality can compensate to some degree to not having access to all the content in the world.
