J.P. Morgan and Wells Fargo are snarling the flow of data to popular financial manager platforms. It's very clear that banks fear this growing competition will take away precious customer information (and possibly the customers themselves), but perhaps the real fear is for customer security and the risk of overloading their own servers. Whatever the reason may be, this move by the banks could prevent the competition from gaining access to data, but it could very well cost these banks some customers who have already placed their trust in the growing number of startups providing financial planning and budgeting options.
