Then it's very common for forks of other software, or software that is meant to compliment another program, to humorously reference the original program. The examples are numerous.
"Brogrammer" is a very recent neologism that originated out of a perceived frat culture amongst primarily (surprise) web developers, but it's still mostly used to describe a hypothetical bottom of the barrel person, rather than any seriously observed overtaking of programming by immature frat boys.
"Bro" dates far before that. I think it's perfectly valid to use it as a pun on "man", which originally stood for "manual", yes. But that's how word play works. The GNU Project hosts jokes like these on their site, too. I haven't heard of anyone complaining.
If you can't stand it, alias it. But being dramatic about it is ridiculous.
The point here is to illustrate that none of this is offensive. But rather, it's being creative with language.
