so because they say that they wont scan your images, you just trust them? the fact that Apple had planned to is evidence enough that they could and possibly do. again, there is no way to prove that they don't.
do you understand what i'm saying when i say "e2ee is almost meaningless on a closed source app"? you are taking their word on whether they know your private key, or even encrypt your data at all. to encrypt a file properly, use a local opensource program (gpg) before ever letting Apple touch it.
btw, have you heard of the case where a persons picture was flagged as csam, when it was sent to the kids doctor in lockdown? these filters are not perfect, and can ruin someones reputation. any pedophile with even a glint of common sense would avoid proprietry spyware (iCloud) anyway, or at the very least encrypt manually.
again, your privacy is being eroded in the name of "saving the children".
look closer. its there
