Is the association that some people will make with "brogrammer" culture a bit unfortunate? Sure. But there's nothing about this program that's making any assertions about bros, or their gender, or anything else - heck, it's not even really talking about people, it's just a play on the word 'man'.
And if we can have a woman named Siri who lives in our phones who answers our questions, why can't we have a bro who lives in our computer and helps us out with the command line?
