PRISM is/was a small program. "Upstream" programs is the what most should be worried about and goes sort of around companies (and anyone/anything else).

Though, some companies are handed a court order to "share" their data (quarterly, about 80 companies so far). And NSA has standard rates for this.

They don't "share" the data, and the NSA doesn't pay for it. The slides clearly show that the data requests are consumed by the FBI, which is the organization that the companies deal with.
