Think it over: the Qur'an is sacred to 1/4 of the world, banning any holy book is PR suicide, and the Qur'an is legal in the PRC.
The developer of this Qur'an app probably tweeted this tweet in good faith, but that just makes it misinformation instead of disinformation.
what do you have to back your assertions
The other assertions I made were that 'the Qur'an is sacred to 1/4 of the world' and that 'banning any holy book is PR suicide'. I can't muster enthusiasm to defend those. They seem clear-cut to me.
As I read the original tweet, it sounded like Apple had banned the Qur'an (ie: its contents) from the its store in China. But that is the dev's conjecture. I'm sure Apple banned his/her particular Qur'an app, but there currently are too few details to know why.
He appears to not be a Chinese citizen. Foreigners are banned from engaging in a whole lot of religion-adjacent activities in China, including publishing religious texts. http://www.gov.cn/gongbao/content/2000/content_60501.htm Article 17, item 6.
Unfortunately I seem to have turned conjecture from someone's tweet into a large thread which was the opposite of what I wanted. We have some developer's speculation and now we're all debating and theorizing about it (which why social media is a $%#* pile of rubbish).
Perhaps next week Apple Developer Relations will get back to this dev with more specifics.
Perhaps next week we'll find same is happening to other people's Qur'an apps.
But at the moment all thousands of us people discussing this tweet on social media are just bumbling around in the dark.
