@evan …
it'd be easy enough for same insiders leaking other details to WaPo to testify, "DMs *were* accessed for Weiss" if they were.
that WaPo only engages in artfully-arranged speculation here implies they have no such testimony.
that said, given the architecture flaws & decade-plus laxity at Twitter Inc, it'd be reasonable to assume DMs probably have & will be accessed for flimsy purposes.
I just don't think it's fair to declare that as a certainty in particular cases where not sourced.
