> Once that happens, it will only be a matter of time before it will be mandatory for CSS to happen at the OS level. Yes, but this may in fact take much longer that it may look at first glance. Think decades, not years. Do not overestimate churn. Compare to how long it took / is still taking for virus scanners to become integral part of Windows. Similarly, at some point it will become empirically clear that CSS (like virus scanners) aren't the end-all blessing they promised to be. There will be accidents in the mean time. Obviously: false positives, misuse by oppressive regimes. But also: malware, DoS, exploits and other mischief we've already seen in the wild with virus scanners, spam filters, intrusion detection systems, DRM, corporate firewalls. I'm confident that at some point, legislation will be loosened to aim for more realistic goals. Especially once legislator realizes it fails to meaningfully "protect the children and fight terrorism".
