Really shitty to publicly announce a firing, regardless of how much of an imbroglio has formed around the situation. I think it would've gotten out without the press release, enough people are watching. Hard to see what Sendgrid gains by officially announcing it.
Congratulations, internet; a completely banal, pointless disagreement with zero stakes has ended with reputations tarnished, factions formed, threats hurled, feelings hurt, and two people out of work- and still nothing has been solved.
edit- this went off the front page REALLY fast, wtf
