For a complex issue this document does a really good job of listing the various problems with this 'scan everything for CSAM' approach.

On your next trip overseas, you can expect big problems. Machine-generated reports on your communications may have been passed on to other countries, such as the USA, where there is no data privacy – with incalculable results.”
