The telcos (AT&T, Verizon, etc...) were cooperating, but that also fell under existing wiretap laws-ish and was known-ish. There had been rumors about it for years, there have been photos of mysterious governement vans of equipment showing up at sites, special locked rooms, etc... Those companies also haven't denied it. However there is none of that for any of the other companies listed under Prism. Later leaks from Snowden suggest that the companies listed in Prism did not know they were part of Prism (places where inter-dc traffic was being spliced, that sort of thing). Also just practically speaking with how fast companies rise & fall in this area doing this on a per-company basis wouldn't scale. Like when would you expect the NSA to approach, say, WhatsApp? Or Snapchat?
