@Stevey.... of course they are against it. Just because they do some de-listing themselves is not really the point. Google can choose what they want to display on their own website. If you have a website, would it be fair for me to judge what you choose not to put on it? That's just ridiculous. The real issue is that acts like SOPA is that for their legislation to be enforceable, the core privacy of a citizen must be violated. A quick example is deep packet inspection, which is what china and a few other countries currently use. It allows ISP's (and who knows who else) to actually decompile the payload of your transmitted packets through their central hub, in effect spying on anything you send through the web that is not encrypted.
Even ignoring that, google privately choosing to de-list certain sites is a completely separate issue from a government entity ordering an entire country to do so.
