The ad said "You wouldn't download a car, would you?"
To which my reaction, and probably that of most people in the audience, is "Are you kidding me??? Of course I would if I could!"
Most people have an aversion to physical stealing, but most people are also happy to get a COPY of something for free, even if it's illegal. That's what reality boils down to, and I can't see anything changing it.
I understand your moral argument, and I don't disagree - there's nothing ambiguous about it. But if you could "download a car", for free, with no fear of repercussions - are your convictions strong enough that you would still choose to go out and spend tens of thousands of dollars on a "real" car?
