Why does every single thing need a unique name? Even trademarked names for businesses and products are scoped to business sectors - its why apple the computer company who took the name of apple the record label was just fine (until apple invented itunes and had to buy the record label). Heck even code does scoped naming... the compiler can't really handle punctuation that is slightly wrong and even it allows me to reuse variable names in the same program. I don't know why we'd need a univerally unique name for each piece of software ever created. The existing software called robinhood is unrelated to this load balancer, so even if I could download and use it, I doubt I'd have much of a problem distinguishing the two.
