Some certainly but to describe that as teh default reason is rather, well uninformed.
I torrent, but I also purchase, in fact out of every friend I have I purchase mroe media then anyone.
As I stated above, I have purchased almost every single US release of the various treks, in formats of VHS, Laser Disc, DVD, Blu-Ray and itunes mpeg4.
Trust me artist get their income off of me.
And there are very few souls out there at least in the US, that have not at one time or another enjoyed pirated content.
Be it from tape recordings of LP's back in the day. Letting others ever listen to those (crime). How about every recording something on VHS back in teh day and taking and watching it in another address? At a friends, ect. Letting someone borrow something? All crimes.
Hell a mix tape given to you (back in the day) is a crime.
For myself I did it because its far faster then ripping a digital copy off the bluray (also not legal). Even as I will when they become released purchase a digital copy.
Look at TAR, it's in the last 2 years finally getting some digital and DVD releases, and its been on the air since 2001. And I have every legal copy I can of all of them (including digital copies in regular and HD).
I don't feel bad that some have been unavailable in any legal form to watch in over a decade.
Supernatural, why. Because my affiliate sucks. With sound and video going out frequently. Its also a standard cropped version stretched to 16:9. Yet I have every season on DVD and Blurya. I have each episode purchased from itunes in both regular and HD formats.
I don't feel bad about it.
