I have the opposite perspective: management made the right call pulling the plug on Mint. The problem with Mint is that it most likely loses a huge amount of money; from what I've read, most data aggregators charge a fixed amount per account + a fee per API call, so they have to recuperate their costs by selling ads.
That's why Credit Karma makes money: credit card/loan/insurance referrals are worth insane amounts (I've heard numbers like $100+ per sign up for premium cards, even more for insurance/mortgage), so it only makes sense to shuffle customers over to Credit Karma where the sales funnel is much more effective. If one credit card referral can pay for the customer's API calls for a few years, it only makes sense to aggressively push for it.
