I agree, I'm also usually the one person arguing in favor of high framerates, I find it silly when people pretend that vinyl records are in some way "superior" to digital and so on. But I don't really see the website going out of its way to say that this look is the way it should be. Maybe a bit of light marketing speak that is talking to people who like this. I don't think there's anything wrong with turning a necessity of the past into a style choice of the present, now that we can do basically anything we want. Pixelized games are a popular thing, cel-shaded graphics even when there's no need to actually draw anything by hand, black and white used to be popular in film making long after color had been introduced. Also I think the "empirical data" isn't as much an argument for using the style everywhere, rather for the effectiveness of the plugin.
