Once again,
I PERSONALLY THINK IT'S A PERFECT ANALOGY
I am perfectly wrong, but stealing is stealing, whether it's an idea, a patent, a digital copy, music, software, etc.
If you obtain it illegally it's stealing and you are a thief.
You are 100% correct, it is theft.
These people who try to justify themselves are nothing but common thieves.
There is NO justification for illegally obtaining software that you should pay for. If you want it buy it.
