Adding Blackberry was just like a private forum in that it's users data was kept inside the corporation on private servers and outside the view of governments.

Adding Blackberry was just like a private forum in that it's users data was kept inside the corporation on private servers and outside the view of governments. That is a threat to many third parties that would love to have visibility into that data for a myriad of nefarious reasons. The same switch-over also happened with internal systems moving to Google docs and other centralized monitoring. I would love to see a chaos monkey test of all the big centralized systems going offline to see what breaks.
