>If I steal an apple from you and grow more apples from it and give them away, there is no difference to the act of stealing your apple and eating it.

Certainly, but we talk about digital good here, stealing the first apple harms me (unless if I was not going to use it regardless), copying it however does not.

>RMS seams to be totally against "stealing" digital GPLed code.

Please explain what you mean by stealing here. He is against taking GPLed code, modifying it, compiling it, and then distributing the binary without distributing your modifications. He has no problem with selling the application/code. He has no problem with keeping the modifications to yourself as long as you do not share the binary. He has no problem with distributing the unmodified binary and/or code.
