The main thing I take away from reading that email trail is that they really need to get Bob some lessons on basic email etiquette.
If that really was the first message he sent to Azer there is no surprise he responded in the way that he did. If you speak to people in a disrespectful way straight off that’s what you will get back.
And seriously who says “We don’t mean to be a dick” at the start of a professional email. It reads like an argument on a forum.
TLDR: Don’t blame Kik, Don’t blame Azer, Don’t blame NPM. Blame Bob.
