Nobody's arguing Adria doesn't have the right to post what bothers her on her blog. Just as much, the community has the right to vocalize their disagreement with her actions because of their potential consequences. On Twitter and elsewhere, many women have been criticizing her, not just for her overreaction to a type of humor they themselves use, but also because of the backwards effect on gender equality in tech this might have.
That said, the biggest question for me is why she seemed so upset by the joke when she made the very same type of joke in public with a friend. I'm finding it very difficult to see where she's coming from because of it.
Adria has the right to post what bothers her on her blog. It is her blog. Read it and get over it.
No one should get fired over this, and Sendgrid does not have to respond to something this trivial. If playhaven really fired Mr-Hank over this, then it's probably a shitty place to work anyways. I work in a place where no matter what mistakes I make, TokBox will always have my back.
This incident should not even be trending on Hacker News. What value do we get out of this other than suppression of free speech and finger pointing?
