Earlier quoted context omitted.
If you 'opt out', service providers can prevent you from sending anything under these new rules. You might not even be able to reach out to support to complain without consenting to your messages being scanned.
So what is the difference of opt-in and opt-out here? In both cases, they identify and scan something. Not sure, if there is out at all.
No, as I understood the GP comment, if you opt out there won't be anything for them to identify and scan, because you can't send anything.
> Not sure, if there is out at all.
Sure there is: You can opt out from being on the Internet.
