Note how all of the results are all about men and manliness, which is fine for gendered products and clothing, but doesn't really make sense for a piece of server monitoring software.
i think whats interesting is that people who use sentences such as "for the modern man" don't think about man as male at all and don't intend to offend anybody.
It's only picked out by the ones who feel oppressed by gender issues (which are often males defending females - in fact, genetics also makes us behave that way, ironically.)
Of course they don't think about, and obviously they don't want to offend, and that is why some good people point this out, so that people think about it and pay attention. Sometimes biases are so entrenched that we don't feel them. They feel natural, and therefore neutral. But, if you want to make a change, than it's precisely those seemingly natural things that you need to change.
You can keep using "man" or not, but I think it's helpful to pay attention.
Frankly, i think some people just like to complain about gender issues when there isn't much going on.
In some languages (ex: french), everything defaults to male-centric. Nobody cares or feels offended by it, and females have exactly the same rights as males.
