I believe the assumption here is that this is a bad thing, and it may be, but I'm trying to keep an open mind. When is it OK to charge different cohorts of users different prices? Why is it ok in some instances, and not in others? If we charged white hetero males (of which I am one) more than everyone else, would that be OK because they are NOT part of a minority? To give a bit of context of how I'm looking at this for our business, we're in the sleep tech space, and lack of sleep is a huge issue in the African American community due to socio-economic reasons. I've got some designs on how we can offer African Americans a lower price on our product than other user groups. I doubt there would be a "backlash" because it's a discount, rather than an increase in price...which is really just perspective...
