Assuming the user trusts Apple, that may be palatable to some. But the crux is, the images they're matching against are in a database maintained by an unaccountable nonprofit (NCMEC). Apple did this so their staff wouldn't have to see the offending images, until/unless it was actually confirmed. However, the matching is all algorithmic and who knows what's in the CSAM database. It could be images of police brutality so law enforcement can ferret out protesters, for all we know. Want to round up all communists? This is an easy way to do so.
