I'm in Hong Kong, I don't get what you mean. There's no porn or snuff movies on it here either, how tame is it in the US ? I bought it for my 5yo to get her Disney dose, do you guys buy it for even younger children ?
What other countries do you think exist outside the US? Why are there "different animals" of Disney streaming services ? Have you pursued your thought down to even quoting a few examples of what you imagine would happen in Tokyo, Johannesburg or Milan if you started Disney+ ?
In the US it's trying very hard to appear kid/family friendly. To the point where the Disney+ versions of PG movies and many TV shows have extra censorship (you can look around online for lists of content that's been bowdlerized on Disney+)
