The fact that these legislators don't see those immediately-relevant cases you mentioned as being enough gray area to put doubt in their mind as to the effectiveness of the legislation really doesn't speak well to their comprehension of how the internet works. It's really sad.
I'm only aware of a handful of senators (maybe the macaca jackass, or perhaps santorum) that have been in any way hurt by not knowing how the internet works. I wish they were so incentivized, but they seem to be following the incentives they have.
