I think Adria is in the wrong here but I don't think it's her fault or fair to blame on her that his employer acted even more quickly and foolishly than she did by firing him.

This whole situation sucks but let's try to be realistic about assessing blame. I understand why the fired individual's name is being withheld but I'd really like to know who his employer is. I would boycott that company way before I boycott SendGrid.
