US curbs WeChat transfers, freezes TikTok as deadline looms
The restrictions are aimed at business-to-business transactions with WeChat and Tencent and will in the first instance affect service providers in the US that maintain the functionality of the app. Over time, however, ordinary users will find that the app's functionality will degrade, according to Drezner.
WeChat is used by about 1 billion people globally and about 19 million people in the US, according to the users group.
"As a 'super-app', WeChat users also rely on the app to make telephone calls, hold video conferences, upload documents, share photos, and make payments," the users group said in its complaint.
"It has become essential to the conduct of daily life for its users, many of whom regularly spend hours each day on the app."
