I think one thing that struck me from the linked article was the point that the memo wasn't structured to invite discussion. It wasn't "let's have a chat", it was "here's an evidence bomb of how you're all wrong".
I think advancing points is fine, but if you're after productive discussion rather than an adversarial debate, you need to proactively invite discussion. And if an adversarial debate was what he was after, that does strike me as inappropriate work communication.
