One thing that comes to mind is how do you define "illegal" content? A huge hangup here tends to be free speech - lots of legal free speech is not legal in places like Europe - e.g. there generally isn't a concept of hate speech in the US, and in the US inciting violence literally means "lets go over here and beat these people up right now" - anything less tends not to be inciting violence. Europe tends to be a lot more restrictive on these fronts.

And if you want the bar to be "illegal anywhere", then places like China would make a lot of things illegal that everyone in the west would be fine with. If you want to say that of course we wouldn't pay attention to China, now you're back to picking and choosing countries likely based upon arbitrary metrics.
