How is it possible that beef, dairy, and chicken are front and center while Lentils, Tofu (or even just soy), Chickpeas, Nutritional Yeast, Broccoli, etc are all left off? Why do they arbitrarily split "protein" and "fruit/veg" given that most/all of the most protein dense foods are vegetables/legumes? Steak is a terrible source of protein (in terms of nutrient density). Immediately pretty suspicious.

Beef has ~3x more protein per gram than legumes. It is much more protein-dense than vegetables or legumes.

Similarly, it's a "complete" protein, whereas most vegetables and legumes are missing necessary amino acids.

The downside of beef isn't the "density" of nutrients: the downside is high saturated fat. Chicken breast, though, is similarly high in protein without the saturated fat downside.

In practice, there's no evidence of amino acid deficiency in vegans/vegetarians except ones that restrict even further (potato diet, fruitarians, etc) https://pmc.ncbi.nlm.nih.gov/articles/PMC6893534/

Besides the ever-popular soybean being a complete protein, if you have normal variety in your diet, it's just not something you have to worry about.

That is not what your linked article says. It says there is not evidence of protein deficiency, and the deficiency of amino acids is overstated. Not that there is no deficiency.

And vegan/vegetarian health is really a 2nd order variable here. Vegans and vegetarians could have massive amino acid surpluses and it remains a fact that vegetable proteins lack useful amino acids that meat has. Maybe the vegetarians are eating lots of eggs. Maybe they are taking lots of supplements. Maybe they are actually eating meat despite calling themselves vegans and vegetarians. It doesn't matter. There really is no disputing the fact about the composition of meat/vegetable protein.
