I guess you're partly right tho. Less on the X37-B, but there are a few "Area 51" and "Tonopah" articles. Certainly active disinfo and infiltration of the UFO/Truther/free energy movement was a thing. Used exactly as you describe, to drive people off the scent of actual tech, and discredit them.
For your viewing pleasure I've included a few links to UFO videos:
But I guess you could be right. Considering if this is a military disinfo op. How hard would it be to fake these videos? Probably very easy.
It gets difficult tho when you have real people (like Antonio Urzi, and Slattery, and Sam Chortek and Jimmy Chappie) coming forward with video and saying we saw this and filmed it. The reason is, because if those guys are part of a counterintelligence campaign, they've just publicly revealed themselves, so it should be easy for a group to put some surveillance on them and work out are they really disinfo agents, who are they meeting and communicating with, etc.
I agree that anon videos could be faked, but I'm not sure how I'd run a disinfo campaign that includes public figures, some of whom keep producing videos, and do so in front of large groups of people. Any ideas?
You'll get X-37 for half a page and then a bunch of click baity speculation
