It's not hate (why would I hate a phone), it's ridicule. Reminds me of the term "bulshytt" from Neal Stephenson's Anathem.
bulshytt: Technical and clinical term denoting speech (typically but not necessarily commercial or political) that employs euphemism, convenient vagueness, numbing repetition, and other such rhetorical subterfuges to create the impression that something has been said.
They could've picked any other word and used it for the same purpose. Maybe an iPhone Pretzel Rectangle, but of course those are more syllables then the marketing team would've liked.
Even with your helpful explanation, I've only a vague idea of what it means; specifically, points 3 and 4. It has "Pro" specifications and it is "Max" size. Professionals use this phone? This is the largest item this company can currently make? ¯\_(ツ)_/¯
These titles mean nothing and I think it's funny.
