In iOS 16.2 Everyone for airdrop can still be enabled to allow users to receive content from anyone, but it will turn off after a 10 minuteand change to Contacts Only. The tweak will require users to explicitly activate AirDrop to receive files and photos from unknown.
According to an online user report Apple says it is improving the AirDrop experience by automatically reverting the to Contacts Only after 10 minutes to help ease unwanted file sharing.
Apple drew criticism for this change, as protesters in China had been using AirDrop to spread posters and other content in opposition to the prime minister or the Chinese government. The Chinese government is believed to have made the change request to Apple, and Apple respect that request.
The default setting of AirDrop is Contacts Only. A user needs to manually change the setting to receive files from Everyone.
