The main reasons that I pirate(d) is due to DRM. The two main issues I had with DRM are:
I want things to work. When I buy music I want to be able to listen to it. When I buy/rent a movie I want to be able to watch it. When I buy a game I want to be able to play it. It has happened to me quite a few times that when I bought stuff with drm they didn't work, for various reasons (wrong player/wrong OS/wrong country/wrong whatever).
I want simplicity. I want to go online, pay and download. Until fairly recently there were no such options. All options available were Pay, hassle and hope it works (see above). The simple way to get things used to be piracy.
The person whos posts represent opinions that are closest to my opinion(not the part of my opinion expressed above) are those of Chris.
It is simply wrong. Simple as that. When someone risks his own time, money and sanity developing/producing something he is fully entitled to decide how it should be sold. If I don't like it I should look for an other product.
Now, unfortunatly I do things that are wrong as well =/
This game I have preordered for a few reasons. (And now that it is made easy I buy games, movies and music again)
I want to support the project/product
It will be DRM free
I want to play the game.
So in conclusion, IMO piracy is theft, it is wrong, but I still do it every now then and the main reason is simplicity.
