I wouldn't call the word itself gendered. The problem is it appeals disproportionately to men (for a variety of cultural reasons described in the study).
It's not in Hacker School's interest to skew their appeal toward certain groups of people for no reason.
Personally i'm much more concerned with why "i love programming" appeals more to one gender than another, and would prefer to see the cause of the problem tackled first. Abandoning the wording removes any need to have a conversation about things like gender-leaning language in the first place, further burying the issue.
