In the UK, The Online Safety Bill is almost about to become law. Without going into the full details, the government basically wants to monitor everyone's messages to stop child pornography and protect people (and other stuff too).
The problem is, they want companies to scan messages and photos as they are uploaded and to give themselves backdoor access to E2E encryption services.
It's very likely the UK will lose access to iMessage, Signal, WhatsApp etc as they would rather withdraw their services from the UK than break their promise to their users.
