Symphony messaging: WhatsApp to business' ears?

It's official, what many financial institutions have been saying for quite a while is becoming reality: they don't want Bloomberg (or any third party?) to have access to all of their messaging, trading or not related, anymore and hence have decided to team up as equal partners, in a top-notch technology utility that serves the needs of its members, a key to its potential success, to fund a competitor messaging system called Symphony. The network, the link between the bankers and their clients and between their clients and their competitors is what enables them to be and stay in business: A third party cannot be invited around that table. Not only, Symphony could be offered to other business sectors as a professional WhatsApp. Follow me here: financial institutions don't trust anymore a third party to manage their messaging data, but think other business sectors will trust financial institutions to manage their messaging data. Although I personally got annoyed when my bank asked me why I was spending some of my savings‎ on our family farm when I asked for a mortgage, I know they probably know my financial situation better than I do, and that I am not a potentially "good" client for them: I trade myself, have little savings, do everything online, so I guess it's only fair for them to ask. Of course Big Brother is watching me - and so should he. But I am not sure if I would send all my WhatsApp messages on a bank-owned competitor system, would you run the risk that your bank could potentially see all your messages? In the case of corporations and businesses though, things are slightly different: their relationship with their banks are usually extremely deep, their bank helped them get their first line of credit, maybe introduced them to private investors or helped them IPO. And when they wanted to take part in a big project with a new foreign client they bridged the financing of the project, they helped them offset their FX risk, invest their liquidity and manage their treasury... so if they started potentially seeing their employee's messages to their clients or suppliers, would it really make a difference to them? Probably not. Of course I am extremely simplifying the potentially extreme risk such a system could have; It has been created on the back of a highly secure encrypted internal system Goldman Sachs had developed and has been enhanced with the best of the best (it is said) technology, in an open source environment. We'll be make sure to test it as soon as it is offered to the public later this year and am waiting for the next Instagram for finance.
