Elaborate about which part—Google Maps app being obnoxious? The linked article makes a strong case for that—common actions are a number of slow steps, the information that people are actually looking for is missing or difficult to discern, etc. Or that I can use it? That's because I don't live in one of the 8 cities that Citymapper supports, whereas Google Maps works on, I dunno what % of the world, but I'm guessing it's pretty high.
Except it's really not designed for that. It's designed for people who know where they're going and how they're going to get there. I don't know, I get in my car, punch in an address, and GMaps does a pretty darn good job of finding a route. That's what 95% of us want.
You know, you're going to have to actually elaborate on that.
