Evidence of aliens would be one of the biggest humanity's biggest events. It would not be a national security issue. "Military hiding evidence" and "population could not handle the truth" is movie and tv-trope. Any scientist looking for evidence would have a duty to inform the public relatively soon, no matter how classified. I agree with Avi Loeb that astronomers should look for evidence of intelligent life as well as natural objects. But the likely alien artifact would not be some stuff that is always a smudge with many good alternative explanations even when sensor technology continues to improve. The most likely source of evidence would be from astronomical observations. Not from earth. The report is not ruling out aliens. It's not even mentioning them. Not feeding the trolls is a good strategy.
