Is it shallow, or petty, to decide based on name alone? Yeah, pretty much, but there’s probably something, a product or service or site, that the name has made you gloss right over it or jump to it ASAP.
What are some examples that spring to mind for you?
Yes, ubermensch is a loanword in English, favored by cringy edgelords like the founder of Uber.
Do you have a source for your claim that Uber is named after “übermensch”? I couldn’t find it anywhere. Some webpages say that it’s just named after the prefix „über-“.
