<i>&gt; Exposing banking data, with sensible and secure authentication process can only be positive.</i><p>There&#x27;s a pretty huge assumption embedded here. Sure, if there&#x27;s actually &quot;sensible and secure authentication&quot;, banking APIs are great. In the real world, though, nothing is actually very secure, breaches happen constantly, and I think there&#x27;s a solid case to be made that we would be generally happier, wealthier, and more secure if banks were effectively information silos.
