The slackbot responses are equivalent to public shaming for using a widely accepted gender neutral phrase to address a group of people.
This makes 18F seem like a highly PC environment to work in.
I'm not even one to say racist or do sexist things! This just smells ... bitchy I guess?
In reading further about this just now, one interesting note is that "guy" is not neutral, and "guys" in the 3rd person is not neutral, but "you guys" (the second person) is used more generally.

I'd be curious to know if better programmers recoil at the gender-neutral "guys."
