What is your source for this information?
I don't want to call names, but here is something: 1. On-device scanning is leaked by some well-known people 2. It gets massive attention 3. Not long after, Apple releases their announcement in very odd time 4. If you read all of their material, there are typos and some are clearly in WIP level 5. It does not make sense to announce, since there is reserved event for all of this in the very close future
Technical docs often live long term with typos. This is a perfectly timed leak to take pressure off regulation pushes by waving one of the biggest honking carrots in front of Western political establishments.
This has political quid pro quo written all over it, and anyone who thinks this type of backhanded signalling isn't common isn't paying enough attention.
