Without commenting on the reasonability of it, you may want to be aware that a growing population of vegetarian and female tech workers may find these offensive.
Beef dies in the wild too so DEADBEEF should not, I do not care if they want to use B16D1CC instead :) I can't see why CAFEBABE would be offensive though.
...And honestly I guess I don't care? If people are that mad about some levity then I probably do not want to work with them.
If you want levity, why not just use terms that aren't offensive? If you can't think of a joke without being sexist or misogynist, then that's on you - don't blame others for "not having a sense of humor"
