China would be a perfect example of my point: they've succeeded in vastly reducing the amount of censored content available, and the average person has no real desire to work around that.
I really don't get how you think your example disagrees with me - do you think China hasn't accomplished anything there?
Flipping the question around, I’m not really sure how Facebook’s current systems don’t fit your definition of “it’s not perfect but it works”?
I think there's a lot of low-hanging fruit we could easily address with a small increase in spending, and I think it's fair to shame companies for not doing that.
I also think there's a lot of mid-height fruit that could plausibly be addressed with a lot of spending. I think it's fair to praise companies that ARE doing that, but it's hardly a source of shame.
And of course, there's plenty of fruit we're never going to deal with, no matter how much we spend.
I think Facebook is under-spending and missing out on low hanging fruit

They manage to do it in China despite the massive censorship there. https://sg.news.yahoo.com/chinese-vpn-providers-hide-literat...
> it doesn't require a huge amount of resources
Are you suggesting that the Chinese government just isn’t trying hard enough, and if they really wanted to they could stop all dissidents in China for forever?
