Oh quit clutching your pearls, he was perfectly civil.
You're the one trying to downplay things we know weren't at all covered in full by these emails (and we've known that for quite a long time). And know about them since you're downplaying them in other comments in this thread (things like exploring the quizz apps and how Facebook knew CA had exploited the API since 2015, how CA initially said the data was for academic purposes, etc).
The latter part of your comment ("how far should we go, the invention of the printing press?") shows me you're not only crying about being corrected but being disingenuous to push a narrative based on lies. Since you're doubling down and running cover for Facebook/CA/Trump's campaign all over the thread it suggests there's more than plain stupidity and dishonesty as motives.
