While many of these projects have nothing to do with technology, they illustrate a point: PRISM was a great name for a project. The fact that Facebook has a "Project Prism" too is just coincidence.
Palantir is the one that still sticks out the most though. They work for the CIA and their Prism technology is essentially the same as the one in the slides 'combining databases from different sources.' I know they've denied it and Peter Thiel would never do that and all but thats still one heck of a coincidence.
If nothing else, this makes it rather amusing to think of how confused the engineers behind 'Project Prism' must have been when the first PRISM leaks were revealed.
