I personally think telling the public the program was shut down and didn't have great results could easily be a red herring.
Truth be told - if there was a lot of success from Psyops programs, and you were the US military, would you want a lot of people to know?
The way it went in history is that the US started with it to bait the USSR into spending money into a worthless project (which succeeded). Then, the US replied to that with "what if it is real?" There was still a lot of belief in "the paranormal" back then; nowadays we know much more about the techniques behind paranormal scam artists.
I've seen various documentaries on these programs (including about remote viewing and Ingo Swann [1], a scientologist), and from my memory the results of these programs were lackluster. Sure, there were some hits, as there are hits with cold reading and guessing.
Almost guaranteed they're still doing experiments like this.
