One of the problems with leaks is that the natural management reaction to leaks is to decrease the free flow of information within the company.
When I joined Google in early 2013 it seemed like there was a lot more information and technical details shared at internal forums like TGIF than there was by the time I left in mid 2015. In fact, we used to joke that the internal go/stopleaks web page where people reported leaks was the new way to find out what was happening in the company, since TGIF had become basically a press release..
