I think the difference is that increasing protein intake does offset other worse eating habits. So it's not that you need the protein, but there's a small probability that it replaces calories from refined carbohydrates.

Yeah, you do need daily protein but for most people nowhere near as much as they are taking in.

You see these protein bars and some of them basically have a full days worth of the stuff and that is before your other meals come in.

There is the YouTube channel 'Subway takes' where people have about a minute to argue a point of view, usually very funny takes as well. There was one that was 'The Protein fad is basically an eating disorder for men', they aren't far off the mark with that.
