It's worse than that. Putting together a powerpoint can give you the illusion that you've summarized and presented some issue clearly, when in fact, there is no content.

At work, we hired a contractor to do some initial investigation into a scientific problem for us. After spending some time gathering data, they gave us a summary powerpoint as the final report. We pushed back hard, saying instead that we wanted a written summary.

When it came back, the results had changed. By forcing them to actually put the summary of the data in writing, they were forced to spend longer thinking about the data, and through that analysis, they came up with a more accurate answer.

"You can't really equate software and music/movies."

Thats where you're wrong, software do equate music, movies and photos etc. When you buy software, you get a bunch of bits with no promise that it will do anything at all. The only thing it has to do is perform roughly as stated in the brochures and its advertising laws that stands between you and a pile of worthless ones and zeroes, not copyright.

A new form of copyright with mandatory guaranties from the manufacturers would differentiate software from media but today, its exactly the same.
