"legal forced me" and "permanent evidence locker" = these texts are part of a legal discovery process (e.g. somebody sued Apple and their lawyers get a certain kind of access to Apple's corporate data)
If there's value for the other side to present the boob pictures as evidence in trial (e.g. in an attempt of character assassination), it will be rather hard to have them not passed around in court now that they're part of the "evidence locker" (as they call it) even though there were 100% personal and unrelated.
