And they wonder why people pirate.
Unfortunately pirated packages are often filled with malware. Not exactly what you want. So a much better choice is just going with open source. Picasa, instead of iPhoto, etc...
You are not buying the disk with the data, you are buying a license to run the software. Even when you pirate it, the license should still apply.
I understand than with P2P networks, you are distributing the file while downloading and that's when they get upset.
Re: downloading, the EFF's Fred von Lohmann says it's probably infringement[1], and so do the media companies, of course.

Ethically I think it is obvious such a thing would be completely reasonable. Technically almost certainly not.
