I hate that this is totally the opposite of how real conspiracy people think.

Edit:clarity

They genuinely believe this is some Capricorn 1 style psyop with an empty rocket. Once the rocket leaves their view, "we're just supposed to trust NASA to tell is what's going on?" Which, sadly, isn't bad logic in is face, but during the Apollo missions, it was possible to use third party radio telemetry to prove they were, at least, in orbit.

Reverse the roles. The standing one is the conspiracy one saying "You see how much money they're willing to spend to fool us?!" That's legit how they think.
