I'm friends with the person who made emacs.sexy, and that no doubt was an influence. He loves emacs & wants to share it with the world (while vim.sexy clearly has a big element of parody to it).
I'd forgotten about the awesome tron legacy article he linked until I saw this.
"Dudebro startups like yours get shit from angry feminists all the time. Using Vim will put a stop to that. Vim donates money to children living in Uganda. You'll look so accepting and humanitarian just by using Vim ... Don't get me wrong: I know you don't actually care about human rights and social issues. All that matters is that you look like you care."
