I didn’t say they were against either. I said their opposition to iMessage parental control features as a change to E2E encryption translates directly to other messages client safety features that may reveal the content of communication to a third party. (Nobody in the discourse seems to take their FUD about iMessage seriously, given that the focus has largely been on known CSAM detection.)

In particular, you can be concerned about E2E encryption being compromised while still believing parents should have some transparency over whether their kids are receiving explicit images. Not clear EFF offers a solution that meets both, but I did not say they are opposed to the latter.
