Why do you say that? They just pulled a cheaper sku leaving the more expensive one, no?
The RTX "4080 12GB" and "4080 16GB" were much further apart in cores (IIRC a 30% difference) and so naming them in the same category in a way that suggests the RAM is the primary difference, was widely seen as disingenuous.
Yes technically any consumer could lookup the specs, but that doesn't still make it a dirty and dishonest move.
