That's true, but I quite like the keyboard it does have. It's not quite as solid as my old 2012 MacBook Pro, but the difference there is subtle. I've only typed a few paragraphs on the modern MacBook Pro keyboards, and didn't find them too offensive, but would prefer the one on the XPS 9570.
That Dell makes you scroll down 3-4 screenfuls to see what keyboard it has tells me a little about who their target market isn't.
