At the absolute minimum at least in the music industry, piracy with Napster woke the industry up to the large demand for digital music. And since the digital stores like Itunes and Amazon are competing with free, I believe that has actually lowered the price. Would we still have digital options to purchase music if it weren't for the pirates? Sure but something tells me we sure as hell wouldn't be seeing songs for .50 or full new albums for $5.00. Pricing would be the same as it is now or would more closely resemble traditional CD pricing.
Do you honestly think that if CD's were still not able to be copied and the music industry had complete control over how/when/where and how much it cost to do so that digital music or CD's in general would be any cheaper? There'd probably be HD-Audio CD's that cost $30 like movies.
I'm not trying to say piracy is good and do see that in a way it is stealing. But there are many times that I feel it's completely moral/justified to pirate something. Any music I've bought before whether on CD, tape or 8 track I would have no problems downloading. Actually anything I have payed for I have no problem downloading.
Now I'm a pretty hardcore gamer and have bought in just the last 2 weeks, Uncharted 2, Brutal Legend, & Borderlands. All new release $60 games. On Nov 3'rd I'll be buying another one Dragon Age. I will be buying for the PS3 but I will be downloading it for the PC. I've also bought both of the prequel books at $15 each. Now am I a filthy thief for "stealing" the PC version? I've already payed $90 for the game and story. There are plenty of moral reasons to pirate. I've had to download games that I've purchased but ruined the disc for.
I've also downloaded software that I haven't purchased but never would of. Photoshop is a great program and fun to learn but I sure wouldn't spend $600 on it to play around on some family photos. Why photoshop? Cause I was given the Total Training instruction videos for it and like learning new things. I don't think they would've worked for GIMP all that well. I've downloaded Visual Studio to learn to program because I sure didn't have the $1200 to buy it from Microsoft and that knowledge has helped me progress in my job. Visual Basic mostly for Excel Macros in work but I only know that because I pirated the software I couldn't afford and taught myself. If I was a business making money off of either of them I would have payed. As it is I'm entirely self taught. I don't have a great high paying programmers job, but I have a decent salary and don't have overwhelming student loans to deal with.
So basically I've pirated a lot of software. But I buy a lot as well. I have over 200 CD,s over 200 DVD's. at least a dozen blu-rays. I've pirated Windows but use Ubuntu. So just how is that I'm making you pay more? Cause I have absolutely no guilt when I download something. I pay more than my fair share.
