Bluetooth, AirDrop and such file-sharing services are crucial tools in China, where the so-called Great Firewall has resulted in one of the mostly tightly-controlled internet regimes. In recent years, anti-government protesters have often turned to AirDrop to organise and share their political demands. For instance, some activists were sharing anti-Xi Jinping posters using this tool on the Shanghai subway last October - just as the Chinese president was awaiting a historic third term as the country’s leader.
I doubt they will. They already added a 10 minute limit in airdrop for the “receive from everyone” setting (China first, now worldwide). From a security perspective it’s a good change but it does block the usefulness of airdrop as a tool for mass messaging.
