Earlier this month, Apple restricted the use of AirDrop in China, which protesters had been using to evade censorship. AirDrop allows local connections between devices, meaning it cannot be monitored or censored by local authorities. However, Apple launched an update to the app in China that restricted usage to just 10 minutes, making it harder for protesters to communicate with other activists, as well as send messages nearby bystanders and tourists. https://www.activistpost.com/2022/11/apple-turned-off-protest-communication-tool-right-before-anti-lockdown-uprising-in-china.html
