No, according to Snowden's documents, PRISM is a data processing system that consumes data sent to the FBI's Data Intercept Technology Unit following a Section 702 order for communications sent to or from a specific foreign user not in the US.

The wiki page's synopsis are contradictory as usual, but the original images as well as Snowden's comments are not ambiguous. The slides show real time access to video, voice, VOIP, etc.
Snowden's synopsis was, "In general, the reality is this: if an NSA, FBI, CIA, DIA, etc. analyst has access to query raw SIGINT [signals intelligence] databases, they can enter and get results for anything they want."
Quoting Greenwald who received the information and disclosure directly from Snowden: "...even low-level NSA analysts are allowed to search and listen to the communications of Americans and other people without court approval and supervision." Greenwald said low level Analysts can, via systems like PRISM, "listen to whatever emails they want, whatever telephone calls, browsing histories, Microsoft Word documents. And it's all done with no need to go to a court, with no need to even get supervisor approval on the part of the analyst."
For the specific users whose data was requested in the Section 702 request.

Funny how Snowden didn't have any evidence of this. All his documents match the description I gave you. The FBI's DITU is right there in the system diagram slide. This is just a misunderstanding of the documents by a low-level sysadmin who never actually saw the programs and a credulous reporter who didn't even try to check his facts.
Why? Apple is legally required to hand over the court ordered data whether or not they participate in the FBI's data integration program. By implementing a proper data integration system, Apple can standardize audits and alerts and make sure the FBI gets only what is required and not somebody else's data by accident as might happen if the data were sent by hand each time.
