Fine as long as we recognize that taking to oneself (Google for instance) the task of policing content will increasingly become a minefield - a rod for their own back. Irrespective of the rights of a private company to do what they wish (of course they can), the message is: 'we'll decide what you can see and say because you're not to be trusted to make a judgement. We're your moral custodians'. It might take time but someone should see the massive opportunity here.
