One of the things we learned from Congressional hearings (from James Clapper and others) and from whistleblowers like William Binney and Snowden is that these intelligence agencies change the meaning of words. Things like "collection" and "analysis" don't mean what you think they mean. When they say "we don't collect X" that just means they don't collect X under the program they're testifying about. If there are other programs, they won't tell you about those or will only testify in secret. Sometimes they outright lie about things too as we found out from Clapper's testimony.
Anyway, don't believe a word they say. This data is way too valuable to be abandoned. If not the NSA, someone else will be collecting it, analyzing it and disseminating it through some database within the IC.
