When I read the article I can't help substituting "label on cup" and reading incident as a coffee burn.]
Seeing "we now have an anti-harassment policy!" followed up by "and women are specifically encouraged to attend and apply." makes me cringe.
It doesn't feel like the way to encourage my wife (engineer) or any of the numerous women I have developed software with that the conference is an awesome event.
I am not "in a spot" or "rationalizing it" - I have concrete proof that changes like this in combination with a massive amount of outreach has had an extremely positive effect for the community and conference.
