I have found that this can be a divisive topic.
I do not pay for any non-physical content, that I can think of. I have occasionally given money to content creators directly, rather than pay for something. In total, I have probably pirated tens of thousands, if not hundreds of thousands of pounds worth of content. I have only ever bought one digital album, and lost it after about 2 weeks after it disappeared from my iTunes, who then refused to give me the album again because it was a limited edition and they "didn't have it anymore". They didn't give me a refund.
Don't even get me started on things like iTunes.
Look, if I buy a kitchen knife and then give it away that is my business.
If I copy that knife and give away a million copies, again my business.
Why should a song or movie be any different?
Not to mention Hollywood in particular has well earned a boycott, as have many musicians. Their job is to entertain, not to brainwash our children and idiot masses. I don't think they will ever figure that out, so they should never get paid.
Then there is the argument that ideas and information should be made universally available to all. And in doing so you end up with better ideas and information anyway. This has been proven to be true with Window$ vs. Linux/BSD/etc..
Besides, by the time a decent copy of a movie is available for download (post DVD release), they've made their fortune.
No guilt here.
