I wouldn't trust a corporation of this size to make sure there aren't recurring bugs which cause scanning of things I have on my device, but do not upload to their servers. If the code for scanning, flagging me and reporting to authorities is on the device, then I expect bugs (intentional or not) which will trigger it, even though I don't use iCloud. Put the scanning in the cloud, then I'll be fine with it - I don't use the cloud. Also the scanning was calculating hashes based on content, not just metadata.
