Banks revolted
Facebook saw Messenger as a way to get banking data from its users.
But a report from The Wall Street Journal indicates that Facebook also saw its Messenger platform as a sIphon for the sensitive financial data of its users.
The data it wanted was anything it could not get unless a customer interacted with, say, a banking institution over chat.
However it all backfired when banks found Facebook's methods obtrusive, but the companies also pushed back against the social network. In some cases, they moved conversations off Messenger to avoid handing Facebook any sensitive data.
