I'll admit to torrenting things I have total access to because the particular material that I already pay good money for doesn't run on the device on which I wish to view the paid for content. If your service doesn't stream to linux devices, and your customer is stuck in an airport hotel with only his linux laptop, either stop complaining about torrents or fix your service.
Probably referring to when something is available only in certain markets due to geoblocking. For example, one of the recent Star Treks was distributed in the US by CBS, and outside the US by Netflix.
