Question:
Would Apple report CSAM matches worldwide to one specific US NGO? That's a bit weird, but ok. Presumably they know which national government agencies to contact.
Opinion:
If Apple can make it so that
a) the list of CSAM hashes is globally the same, independent of the region (ideally verifiably so!), and
b) all the reports go only to that specific US NGO (which presumably doesn't care about pictures of Winnie the Pooh or adult gay sex or dissident pamphlets)
then a lot of potential for political abuse vanishes.
