I think you're being lenient with SendGrid because it was a close call and not a full-blown catastrophe. First of all, SendGrid lied about its support staff's permissions. After the incident, SendGrid then sends an "oops! our bad!" e-mail where the employee in question will apparently be gently tapped on the wrist and maybe send a passive-aggressive reprimand.

I mean, keep in mind that this is the same company that publicly crucified a female employee in order to stop a DDoS attack. Clearly there are some priorities out of whack there, and given the insecure nature of e-mail in the first place, I would never want to deal with a company that is so clearly unprofessional.
