This is a pretty common sentiment on HN and other places on the internet that's used to justify piracy but I don't think it really applies to most people who say it. The person in the video is from Buenos Aires and really can't get his hands on movies and TV shows short of going to the United States.
But if you're in the United States and want a TV show, between iTunes, Amazon instant, YouTube rentals, Google Play, Microsoft Store and your cable provider the movie is probably a $2-$3 HD rental. $5-$6 if its just released. If you have time to browse HN you're not poor enough to justify pirating over a $6 rental.
Of course the counterargument is "but the DRM formats don't work on my TV/car/fridge", but that doesn't work here because Popcorn Time is designed for desktop viewing and deletes the videos on reboot, not for transferring to other devices. And "the only movies with high pirate rates aren't easily available" doesn't work either because the most pirated shows are the ones most easily available. Game of Thrones is on HBO Go, Walking Dead is on amc.com, Kingsman: The Secret Service and Seventh Son is on every rental service listed above. [0]
