When has the EU mandated encryption backdoors?
They keep trying it via e.g. chat control
The US has also tried it multiple times. So has Canada. It's been shut down each time. This isn't a unique to the EU problem.
Didn't UK had "The Snooper's Charter" as well?
Encryption backdoors is not a case of extending reach for a government, but an effort to get the capabilities back.
They were able to do that before. They just want to be able to continue now.
Note: No, I don't support the idea of backdoors. On the contrary.
