Here’s my comment via the article at UK Times Online on Slashdot:

 You can follow three paths as a search engine (in simplistic terms):

1) Show everything–this implies crap sites (*coughs* boingboing), great sites (*coughs*

/.), malware sites (3221.com), search results sites, etc. thereupon your results are fully awful, but absolutely representative of what a search engine is “supposed” to show by previous comments, and thus get banned in China thereby showing nothing.

2) Do as you are told–obviously not as fun and cries of shenanigans and submissions are there, but then you get to show more results to people around the world who otherwise would just be filled with pure propaganda.

3) Do your own thing–”hitting the corner of the ping-pong table”, barely get by with regulations without getting punished.

Guess what? None of those are illegal to do under any international law at this point in time (although I recall some events within the US on trying to sue sites that just link to other pages, but nothing for the international arena) and certainly nothing illegal to show or not show within the US for political sites.

Remember, this is a corporation, not a government, so there is no “right” that you have for them to “display” your site in “their” index.

At least all algorithmically anyway.
