I don't think that the period panty product is actually what they're sending to Africa. They mentioned that "the purchase of a pair of THINX also buys seven washable pads for girls in Uganda."

I don't think the majority of startups are out to 'help the world,' though many are out to change/'disrupt' (even this one claims to be disrupting). I don't know that I find that such a bad thing, though. Many products try and fail to change what they see as a problem, but there's really no harm in that. They're just trying to help.
