Part of the confusion is that there are two things involved here; 'Chat Control 1', an existing (but expiring) derogation to the ePrivacy Directive which allows, but does not require, providers to scan messages. 'Chat Control 2', which you'll likely have heard more about, would _require_ providers to do this. The wiki article is quite poorly written and implies that 1 is an earlier version of 2, which isn't really the case.

Anyway, this is about Chat Control 1.
