Since it's an AI company, and not actually doing anything by hand, it wouldn't surprise me if they came up with the name "manus" because it has "anus" in it, and then designed the hand logo due to the Latin meaning of the name. [this is a sarcasm, in case that was not clear]

So it is the Ancient Romans who were obsessed with butts. Got it.

There are more English words that end in -ass than Latin words that end in -anus, so who's really obsessed?

Canonically it was winged penises, but yes.
