Actually, Apple does allow gambling apps in its U.S. app store. But the use is geolocated to places where gambling is legal.

Not sure that outlawing gambling, which wrecks lives through addiction and has no measurable benefit, could be equated to outlawing letting you talk about the fact that your government slaughtered students in Tienanmen Square or simply that your ruler resembles Winnie the Pooh.

Most people in my country think that gambling is basically fine and handguns are a menace to society, so our laws reflect that. It seems bizarre to us that most Americans can legally own a handgun, but can't legally place a $5 bet on a football game. Our attitudes to guns and gambling aren't right or wrong, they're just different.

There are things I could say in this comment that would be a federal felony. No country has absolute freedom of speech. All countries draw a line somewhere. China draws that line in a different place to the US. It's not right or wrong, it's just different.

Being jailed for saying someone looks a bit like a cartoon character or stating simple facts about a government slaughtering students is definitively wrong. The only folks who might disagree are those brought up in brain-washy/authoritarian regimes.

the article is about them removing gambling apps, not about them removing apps that help citizens speak out about their government...

Sorry, conflated this with the recent purge of VPN apps that China insisted on to prevent citizens from talking of Pooh and Tienanmen.

Authoritarian gambling laws, at least.
