From the RIAA side:
In any event, are you suggesting that a royalty dispute between an artist and a label is justification for stealing from both of them? Would you feel free to shoplift a CD from a record store based on that logic?
This has to hold the world record for the biggest strawman argument ever. The RIAA guy is answering the claim "I feel justified by downloading RIAA music for free because the RIAA is stealing from the artists" when no such claim was made, at least that I can see. Are propaganda techniques all they have to fall back on now?
