This is really weird. Everybody on HN appears to be praising this for the clever entrepreneurial idea. I'm kind of amazed that I'm apparently about to be the first person on here to call this out as a hugely misogynistic endeavour. Women should not be treated as a SaaS product.
On a slightly more serious note, this is, in itself, not really sexist in your typical "Internet at large" sexisism. Don't get me wrong, there is some very serious and deep seated (seeded?) woman hating that occurs on the Internet, but this isn't it. This goes way beyond the Internet, and into ancient mores that carry across time and culture, which are definitely sexist, but not the kind of sexist you find in Halo 4.
More like the kind of sexist you find when you wander Amsterdam's red light district. Old-school misogyny.
