Based on said leaks and a fact sheet from DNI Clapper himself, PRISM is simply an efficient warrant processing system based upon legal authority, nothing more. While troubling and worthy of debate, particularly regarding its 702 legal authority and targeting of Americans, it does not involve malware, surreptitious access to any of the involved tech companies, or an infestation of NSA tooling. The author of the PRISM slides was not careful to make this clear, which meant without context, everyone seemed to assume PRISM was a Room 641A situation. It's become clear that to be a 'partner' in PRISM simply means that the entity is capable of responding to warrants using the system, and citing PRISM as an example of compromise in the same vein as this Huawei announcement is disingenuous at best. Some companies built systems on their side to help (like Facebook), while Google delivered their PRISM data via SSH, for example; Twitter, interestingly, did not play ball. Having responded to warrants before, I can tell you that it's a drawn out, paperwork-intensive process. Something like PRISM is actually net good for both parties, since governmental relationships are extremely human intensive on both sides at the scale of the large tech players. I can actually understand and sympathize with the USG designing a system to make it more efficient, though the leaks tell us it was flagrantly misused (primarily via NSLs, back door searches, and so on).
