Don't make the mistake of looking at what it does to other people. Look at what you are doing, your actions. I can't see how you taking something that does not belong to you is anything but stealing. Theft. Justifying it with the, often false, idea that it did not do any damage, does not make your action any less so.
It is very true that stealing someones car is quite different from stealing a copy of a computer program. Nevertheless, it is the act of taking something which does not belong to you which makes it theft.
How about someone dropping something on the street. You see it falling to the street and the person is oblivious to the fact and keep on walking. Frankly, if you pick it up and keep it it's also theft. The proper thing to do would be to return it to the owner, or at least make it easier for the person to find it.
All these justifications does not make it less so, it only serves to make you not feel so bad about what you have done/are doing.
It is also rather gutless to hide behind justifications instead of simply owning up to ones actions.
The number of people who feel it's not stealing does not either make it less so.
A much better way of life is to stand up for your actions and set a good example. Make it your goal to always be helpful, soon you start feeling better about yourself as well. I'm sure a number of people consider the above weird and unrealistic. It is however totally workable, and usually brings about a much better feeling about self and others. Being unselfish creates something akin to an accounts receivable in life. When you're in need others often come to your aid, etc.
As I've said in the past, BSA and similar organizations, are in themselves trying to make everyone into thieves by calling everyone so in the hope of increasing income for their members. No doubt they are paid more the more they can stack things in their members favor.
Simply observing how certain groups operate around artists you can see that they themselves are raping the artists under the guise of giving them an "opportunity". Meanwhile the artist who is the one creating the art, and clearly the more valuable one, sees only a few pennies on the dollar. While the lesser person who cannot produce art is taking such an advantage of the situation that the artist has a hard time making a living. Regardless of the effects of those actions, it does not however make the act of taking something which strictly speaking does not belong to you any less of a crime.
Again, this disregard for common sense and decency is not an good opportunity to loose your own respect. Ignore what others are doing and do the right thing for yourself!
