The company spokesperson said that WhatsApp complies with U.S. sanctions law, so if it encounters any sanctioned people or organizations using the app, it will take action, including banning the accounts. This obviously depends on identifying who uses WhatsApp, without having access to any of the messages sent through the platform, given that the app uses end-to-end encryption. This would explain why WhatsApp hasn’t taken action against some accounts spreading the Taliban’s message in Afghanistan.
