Very likely foreign or domestic drones. They’re UFOs in the technical sense, but I think using a different word here to be less sensational is likely warranted. The path of movement and speed looks exactly like drones to me.
The people raving about the UFOs being aliens don't want to miss out on the clicks though! As well as them trying to push the narrative that the government is hiding things (like aliens!) from you, and you can't trust it. "Next up, after these ads about gold and these diet supplements, the truth about the so called Coronavirus 'pandemic'!"
