That doesn't make sense. There are 2 versions of chatcontrol:
1. Voluntary chatcontrol (i.e. temporary derogation of the ePrivacy directive)
2. Mandatory chatcontrol (i.e. services must scan private communication once a detection order is issued)
The first version of chatcontrol is currently in effect, but it will expire in a few years. It was introduced, because social media (like facebook) was already scanning private communication to find CSAM and then someone pointed out that this is illegal in the EU and thus the ePrivacy directive was sabotaged to allow the scanning of private communication.
Facebook wanted to have a legal basis for the scanning of private communication. This does not hurt non-EU social networks, it helps them.
