The establishment guidelines on protein intake for decades (since the 80s) have been very minimalist, only looking to balance nitrogen -- leading to guidelines in the 0.8g/kg range. This is what they're referring to. Yes, it's still hyperbolic. But they're not talking about a relatively recent popularity/marketing swing. The new guidance of 1.2-1.6g/kg is 50-100% higher.
