Yes I live here and it seems quite successful. Most smokers I see now in my area (not counting vapes) are foreign Asian students who didn't grow up with it.

I don't think it'd work well online for similar reasons, the internet is global, it would just disadvantage local companies for no real gain due to our population. It would have to be a concerted global effort. I think there is quite a bit of overlap with accessibility too (simple and quiet is easier to parse for computers and humans than confusing noise), so maybe a push in that direction.
