Is Congress Really “close to destroying the internet?”

How worried should we be about this? According to Kos and many others, it sounds like the answer is "very worried." What do you think? Also, am I missing something here or is this an issue that should united the Tea Party, right-wing bloggers, progressive activists, pretty much anyone who runs a blog or website, and a lot of other people? If this bill's as bad as described, why would anyone support it, unless of course they were "bought and paid for" by wealthy interests?
