As this project appears to be fairly unknown in the fediverse still, I’d like to use this opportunity to advertise Flohmarkt. This Fediverse equivalent of Facebook Marketplace already has some instances up and running - see here: https://codeberg.org/flohmarkt/flohmarkt/wiki/flohmarkt-instances
No one is saying you cannot have a good German name. Uber is an American company. Shit company but great name. Comes from German and translates to other linguistic communities fairly well
Uber isn’t a German word tho?
