I suspect they’re jumping on your use of the word “retarded”, since some see using it as an insult as a slur against people with intellectual disabilities. (They also can’t spell “casually” and substituted a word with quite a different meaning, which makes it even tougher to decode what they’re saying.)
It’s niche hardware: a smartphone in a flip-phone formfactor (with a headphone jack). Of course they’re not producing them for <$100. Ars Technica costed out other phones in a similar market category ( last paragraph here ) and by that standard it’s middle-priced, or a bit above.
