He never said that; Good companies can have a good influence without policing anything. And isn't it the job of all honest citizens - not just the police - to stand against "cattle rustlers, bank robbers, and bounty hunters"?
Seems a shame to leave Google to do the dirty work, then criticize them for wanting to be the police.
You can't call for self regulation, freedom etc., etc., when too many "honest citizens" can't be bothered to stand up for high standards - and then attack one organisation that does.
Why do I get the feeling that whatever Google does is going to be wrong, even helping an old lady cross the road?
