People sometimes say nothing came of the Snowden revelations. I think they're wrong. When the NSA mentioned connections between datacenters were tapped, I believe FAANG immediately end-to-end encrypted links between datacenters, because otherwise your business secrets depend on how cozy you are with the government.
I'd even say it may have played a role in Google Fiber. I don't know about Google laying its own fiber because it wants to be nice or because it wants to roll in the mud with Comcast. But if Google was suspicious that ISPs could get Google data by tapping end users, then it makes sense to keep up the pressure, and less sense after getting everybody to use HTTPS. Timing seems to work out.
Might be a load of conspiracy hogwash, but it fits the laws of power.
