Ah what is killing the music industry.
Rather than buy music I listen to the radio. They pay for me. I watch music videos. They pay for me.
I no longer buy CD's because most of what I hear I really dont care less about hearing again. So I will leave it to radio stations playlists. That is what is killing the music industry. I once would buy 2 CD's a month but now I have more music than i can ever listen to. I am part of the decline. My kids dont listen to music as I did so they will never purchase like I did. That is what is killing the music industry.
Notch is firmly part of the PC/IT community. His ideas must be framed that way. What he is saying is pretty clear. Make your product easy to use, fun to keep using, cheap enough for everyone to buy and you do not have to concern yourself with any loss of revenue because you will just keep selling enough stuff to make continuing development worthwhile.
He is very correct when he says Piracy is not a lost sale because chances are the non-paying user was not going to buy no matter what the price. At the same time they probably have amny other pirated copies of other software so that chances are they will not be taking much time with MineCraft anyway.
