That is an interesting article. Their point that Nintendo needs to lower the cost of the Switch to move more units suggests that sales have plateaued, which would make sense given when it was released.
That said I would never buy a console that was digital games-only. It removes any chance of game resale, and at this point, it is certain to make you reliant upon being on their network, if not all the time, then very regularly. And I think media in general is already splintering off into all the big companies having their own channel exclusively hosting their own stuff, to consumers’ detriment.
Imagine a single network that would give you access to any movie, TV show, or game you wanted to experience. One password, one login, one entry point for everything, with a UI that allowed you to filter out all the garbage you don’t want. I think that’s what consumers want and have always wanted. But there are too many lawyers and too much money in the way, so it will never happen.
