Oh my sweet summer child...

This has been the continual goal of the US defense and intelligence agencies since 9/11, which was blamed on a lack of information sharing. Why do you think Edward Snowden had access to everything? Because it was consolidated post-2001.

You think there is any access control at the upper levels of the dark intelligence agencies? They have access to the whole take.

And it used to be that was pretty useless unless you had an actual lead. You'd need a East German Stasi level of labor to read everyone's secrets at scale... Now you don't, thanks to AI.

Snowden had mass access to a mass surveillance program, not mass access to N dark programs or particular bits of high value intelligence. The thing you are describing is primarily around sharing threat intelligence or in other words, spying on us plebes. High value target intelligence and other bits of fun are still kept quite seperate.
