You do realize that the concept of intellectual property did not even exist until the mid 1990's. I was there, I played a part in it, and I remain appalled to this day as to what happened. It made me switch careers.
I'm sorry that you feel hurt by that, but as a programmer, if I create something that works in a very specific way and nobody has ever done it, I want my creation to be protected from replication. As a corporation, they have every right to ensure that their property is not taken and reproduced. You may not agree with it but it is law and it goes further back much further than the 1990's. We have been doing it for years with music, art and literature. This is not a new concept and has been in business for hundreds of years.
Oh, I was there as well as it happened and helped usher it in. I have been working with computers since the 80's and helped to digitize aircraft log books in the Army in 1992.
Anyway, the point I was making is that they still have a right to protect their products. If you created something, you would want to protect it as well.
