I specifically haven't taken a position on what the sightings actually are. I'm speculating on why the government has changed their approach to information about UFO reports. I think they want to avoid the Streisand effect that happens around UFO coverups, and maybe also encourage reporting (because if some UFOs are actually foreign tech (aliens included I guess), they'd want to know)--they can easily do both by getting it on the news as a normal weird thing we hear about and shrug.
