Oh please. The claim they 'changed clothes' in the module was to explain why the unidentifiable persons on the raft were wearing wetsuits and not their space gear. The astronauts on Artemis III had to be prised out by up to 150 guys. Here you have a handful of 'frogmen'. We never actually saw it splashdown, either. OK, so Artemis III was in an especially pressurised module and the crew never left the craft. But the three guys who bounded down the navy helicopter steps could have been anyone at all, or at least they looked as right as rain.
As for the quarantine; that was utter nonsense, too. The word quarantine comes from the Italian for 'forty', meaning forty days isolation to ensure no symptoms of ill health appear. 21 days is a joke, when even the latest Hantavirus and Ebola contacts are forced into legally-enforced quarantine for much longer periods.
I agree the entire thing, especially the interview behind glass was an entire performance for TV PR.
