The claim that "it has done little" is nonsense. It is based on the fallacy that intelligence is only useful if it directly leads to the capture of a terrorist.
However, intelligence that merely confirms other data is useful because it helps us to know that we are working with sound information. Under the above fallacy, such intelligence would be labeled useless simply because it did not lead directly to an arrest.
Intelligence that says that something is
not related to terrorism is also beneficial, as it tells us that we can stop wasting time on it and focus our energy somewhere more useful. The now-defunct phone metadata system was handy in this regard. From time to time the government stumbled across suspicious phone numbers, and the metadata program was able to establish that those phone numbers were not worth focusing a lot of energy on.
Now when the government stumbles across a suspicious phone number that might have been ruled out by the metadata program, they will have to devote resources to investigating the phone number even if those resources would be better spent somewhere else.
