Another comment explains the moon landing one. It’s a hexbear comment and probably not federated to a lot of instances, so copying it here:

The Moon landing line is a pretty important thing to study, actually, since we know what the rehearsed line was: “One small step for a man, one giant leap for mankind.” Without that “a” it’s a very silly line.

Armstrong for years claimed he said the line right and that it must’ve been garbled in the radio transmission, and in recent years has been vindicated as better signal:noise algorithms processed the recording and found the missing word. Researchers aren’t blowing money to find out if Armstrong was a liar, they’re using it to develop more sensitive receivers, better transmission protocols, and more advanced algorithms to parse signal out of noise, all of which have massive impacts in other domains. An algorithm that’s better at parsing data out of noise in particular is going to be useful in loads of places like MRI machines where improving resolution will take billions in research but improving parsing is just updating the software.

Can’t really blame people for defederating though. It’s a slog to find the treasure in the shit. In this same thread there’s both “Death to America” and “kill all honkeys” non-sequiturs. I can see why they drove off their admins in a stupid struggle session recently. I’m just waiting for another struggle session when they discover the etymology of “bad” and have to rename !badposting@hexbear.net:

It is possibly from Old English derogatory term bæddel and its diminutive bædling “effeminate man, hermaphrodite, pederast,” which probably are related to bædan “to defile.”
