The same reason they made iMessage e2ee, which happened many years before CSAM detection was even a thing.
User privacy. Almost nobody trades in CSAM, but everyone deserves privacy.
Honestly, this isn’t about CSAM at all. It’s about government surveillance. If strong crypto e2ee is the hundreds-of-millions-of-citizens device default, and there is no backdoor, the feds will be upset with Apple.
This is why iCloud Backup (which is a backdoor in iMessage e2ee) is not e2ee by default and why Apple (and the state by extension) can read all of the iMessages.
I didn't ask why they would want E2EE. I asked why they would want E2EE without CSAM detection when they literally developed a method to have both. It's entirely reasonable to want privacy for your users AND not want CSAM on your servers.

It literally is the only thing the technology is any good for.
