I meant that there is no global authority for saying which websites are OK and which ones are not. So not really that the legal system in specific countries have not caught up.

Lacking a global authority, Google is right to implement a filter themselves. Most people are really really dumb online and if not as clearly "DO NOT ENTER" as now, I don't think the warnings will work. I agree that from a legal standpoint it's super dangerous. Content moderation (which is basically what this is) is an insanely difficult problem for any platform.
