I would naturally tend to agree with you, and when it comes to DRM-free things (like most music) I totally agree, but I genuinely think financially supporting companies using DRM is unethical. I used to buy (and still would buy) a ton of ebooks and a fair amount of movies/shows, but at this point I refuse to. The only exception is Audible. I still buy a ton of audiobooks from Audible (unless I can find them on Downpour or another DRM-free site) because I think they've gotten to a reasonably happy medium on the DRM. I would rather they drop the DRM, but it's at least not a giant pain in the ass to strip for people like me who really care about that.

I strongly want to pay people for good content, and I think they deserve to make some money for their work, but as soon as they slap DRM on it to limit my ability to back it up, consume it on whatever device I want, etc, the scales are tipped and I think piracy is actually more ethical than supporting such shit financially.
