The Switch and Xbone/PS4 are pretty much going after two different markets. The gamers who buy Xbone/PS4 consoles wouldn't buy a Switch instead of one of those, they'd buy the Switch to compliment the other, because as the article says, the libraries don't differ that much for most peoples tastes. Nintendo platforms meanwhile provide a lot of variety but without major 3rd party support. It's the same as PC and consoles, yet for some reason people understand fine that Nintendo platforms exist for a different market yet can't wrap their heads around the idea that PC gaming and console gaming are two different markets as well, thus we get "lol but xbox has no exclusives!!".
That said, the Scorpio is a gaming console, the Switch is a gaming console, and there are only three in the market. So of course they are all "worried" about one another. But not at the degree this random blogger who posted their opinion on Forbes believes, imho.
