I think to answer your underlying question of ‘why’ a bit.
You say ‘robust’ for societies as if it’s a given positive, but there is an implied statement hidden there.
Robust against what?
Robust against censorship is rarely desired by the majority (and certainly not openly), because the censorship is with the consent (and often at the request of!) the majority.
Just look at the CSAM/Kiddie Porn discussion in the US.
At least as long as the majorities interests and the gov’ts interests align enough, which is usually for far longer than anyone wants to admit.
So as long as it doesn’t step on the majorities ability to get what they want when they want it more than they are willing to tolerate, robustness against it will always be a feature with a limited market and a lot of opposition. An anti-feature in some ways, or at least it will be spun that way.
We may consider robustness against this good - and I personally do - but in my experience that is far from a common attribute, especially if you boil it down to specific examples.
Should Pakistan be able to robustly send how to bomb US targets + propaganda to everyone? Should someone be able to do the same with child porn? Or anti-Islamic rhetoric? Or anti-women’s rights? Or anti-free speech?
