Kutcher:
Placing search engines and ISP’s in the middle of policing for piracy is plane[sic] and simply a bad and confused attempted by well meaning people that fundamentally don’t understand how the the Internet works.
Please note that I’m posting this not because “it’s official now that a celebrity said it”, but because he’s actually got a horse in the race, and is still against it. Ashton Kutcher presumably is a big enough name to get DVD royalties in his contract.
No clue how much Ashton actually understands about the internet, but I do know that everyone who seems to even kind of get how the thing works is against SOPA.
