Apple is being probed by New York’s State Department of Financial Services after angry customers accused the algorithms behind its new credit card, Apple Card, of being sexist against women.

The drama unfolded on Twitter over the weekend as David Hansson, creator of Ruby on Rails, the popular framework for the Ruby programming language, berated Apple for giving his wife, Jamie, 20 times less credit than him, despite them both applying for Apple Card using information from joint tax returns.
