It's easy to look clean when you're just black and white, but leaning on it without thought means you eliminate information. Blue is used in the UI for interaction areas and blue checks in particular mean persons, as opposed to gold and gray checks which are companies and gov institutions. You can have a functional UI in just black and white, for sure, people have been doing this on computers and handheld devices forever. But why? To what end? It looks stark and dystopian and strips an information channel (color) for no good reason other than X is way too serious for... color. For some reason. For an "everything app," X so far is only removing things. People won't recognize anything that connects them to this app one day and they'll move on.
