I think it is pretty important to use different definitions of piracy:
The worst case are the guys who pirate games / movies / music and actually SELLS them! Geez, I hate this people and there is NO excuse for doing that!
The next case is to pirate games / movies / music, use it but never pay for it...
Well I don't like that, too... if you DO like something, PAY for it.
As for software: There are a lot of great free software applications... you don't need word, use OpenOffice! So you don't need to pirate!
I can understand it though if you are under 18 - I pirated myself Amiga games when I didn't have the money for buying... now I own nearly all the Amiga games I played earlier and don't have any pirated games left! I bought them as soon as I earned money!
The companies NEED the money to create good games!
Then we have the case to pirate games which are no longer available (most NES games). Well, it is okay in my opinion, not legal, but as you can't anymore buy them the companies don't lose money at all...
The last case in my opinion is if you pirate something to TRY BEFORE YOU BUY (but you have to be honest in that!)
I'm running a company together with a friend, we started everything from scratch with our own money (Post Production company).
But we had the problem that we didn't know which software would fit our needs best - and one piece of software costs about 7000$, so if we'd bought it but couldn't really use it, we'd run out of money - damn.
So we pirated those programs (or used the demo if there was one available), tested them a few days then bought the ones we needed and deleted the other ones.
This is also okay, in my opinion, though it also isn't legal.
So far for my "different-kinds-of-pirates"-opinion.
I have another interesting aspect to think of:
I know some people who work in the music business.
And - believe it or not, but it's true - a lot of music producers (and I am talking about those chart breakers!) release their newest, often yet officially unreleased tracks using share clients (like Kazaa, eDonkey)!
I asked some why, and they told me that the song is then better known to the public, gets high into the charts when released and sells much better!
Here pirating can really bring money to the producers!
Another interesting aspect is the answer of an audio magazine to the question
"What system will survive - DVD Audio or Super Audio CD?". Their answer was: "The system where the copy protection is cracked first!"
True, as soon as you can copy anything, the system will sell better.
When more people have the system, more people buy original music (well, most people don't pirate EVERYTHING but sometimes buy stuff!)
So pirating can help - but it can also harm.
What YOU think of pirating is your opinion.
MY opinion is that you should pay for stuff you like (I even sponsored some guys who created some really good freeware stuff - in my opinion it was worth every single cent I spent!)
I'm perfectly pleased if one pirates to try something out or to get some stuff which is nearly impossible to find anymore on that planet (like NES carts, e.g.)
But PLEASE don't forget that companies need SOME money to live - pay them if you like their stuff!
Geez, sorry for that long post, I hope it was a bit interesting
