Prism in tech is very well-known to be a surveillance program.
Coming from a company involved with sharing data to intelligence services (it's the law you can't escape it) this is not wise at all. Unless nobody in OpenAI heard of it.
It was one of the biggest scandal in tech 10 years ago.
They could call it "Workspace". More clear, more useful, no need to use a code-word, that would have been fine for internal use.
Is that what you think hitler was very famous for?
The extreme examples are an analogy that highlight the shape of the comparison with a more generally loathed / less niche example.
OpenAI is a thing with lots and lots of personal data that the consumers trust OpenAI not to abuse or lose. They chose a product name that matches a us government program that secretly and illegal breached exactly that kind of trust.
Hitler vegetarians isn't a great analogy because vegetarianism isn't related to what made hitler bad. Something closer might be Exxon or BP making a hairgel called "Oilspill" or Dupont making a nail polish called "Forever Chem".
They could have chosen anything but they chose one specifically matching a recent data stealing and abuse scandal.
Altso, nazism. But different context, years ago, so whatever I guess?
Hell, let's just call it Hitler. Different context!
Given what they do it is an insidious name. Words matter.
