Yes, it is theft. If you keep something valuable you find, which is clearly something someone owns, without attempting to locate the owner... you are a thief or at the very least, a scum bag. And yes, copying is stealing. All you people who think it isn't, are just trying to justify your theft. If everyone copied the one file someone paid money for, then you are thieves. If I hire a team of programmers to create an application, which I then sell so I can pay my workers and myself and you make a copy for yourself without paying me, you are a thief, there is no way around that.

Not true. I bought a mp3 player far before apple ever had one on market. All apple did was have itunes website built.

You shouldn't use a title like that when you have zero proof. You are making up stuff. You sound like the mass media.
