Not my experience, sorry. Worked on linux desktop for 18 years or so. I have a mac, I have to work with it every now and then. Normal development tools (eclipse and all that) are ok but the "slick" user interface is hilarious. It may have a hidden logic but that escapes me. Save dialogs are different from one app to another and some of them will only give me 4-5 directories in which I can save the file. After the last update, the finder does not show all the directories in my home, not clear why. I will never understand why the top menu bar is so popular, my mouse has to travel a lot of unnecessary distance.

I agree with you that this is theft and I agree with you that this makes some people to loose money. I find hard to believe that the efects are catastrophic but again, I don't know any figures and you may as well be right.

What I don't believe is that this causes less diversity. The music business is as industrial as food processing and unfortunately this is based on recipes. Two years ago everything was latino. No matter how good or bad. Now it's dance I believe (I'm not following the trend).

Diversity is exactly what file sharing offers to someone like me.
