I would say that Apple should make some anti Samsung ads like Samsung is making about Apple, but I don't think that people would know who they're talking about without actually saying the name of the company. To most people, I think, there's the iPhone and there's everything else. Samsung is just another name in the bucket.
Apple is iconic. And it's users (at least many on this forum) brag about things like how long lines are for product launches vs any other phone manufacturer/device.
That's the reason Apple can't reverse the ad without naming a rival. It's a double edged sword for Apple fans. They want to brag about long lines (as if that means anything really) but then get upset when there are ads pointing the long lines out.
As I've said before - the fact that the iPhone, at times - is impossible to "obtain" isn't really a plus for me. But then again - I haven't bought anything because it was popular. I've bought the best tech for my use case. If I never had to wait on a line or have a product delay because of how popular it was - suits me just fine.
I love my iPhone 4. But I loved the fact I just walked in when I was ready to also get a Skyrocket and ATT had one in stock. No muss - no fuss.
