"The phones were compromised using an exploit chain that we call KISMET, which appears to involve an invisible zero-click exploit in iMessage"

Why aren't there a hardware switch on the phones that renders the OS read-only during normal use?

How would this work, and how would it help?

Well if the OS is rendered read-only at the hardware level then malware can't take up residence.

The malware would run out of RAM, then. It’s not like the files it’s writing to disk are enabling it to gain persistence.
