It was a not specified but clearly meant part of his question that it's asking in the context of "... that could be tied to decoupling".

Eg this has nothing to do and thus can't be hand-wavy blamed on for things like "On mobile its navigation is terrible, takes you into strange routes that might be technically faster but are hard to drive at or sometimes non-existent. Sometimes tries to be smart, makes everything worse. i.e. suggest a route that it says its 5 min faster and shows no traffic and you find out that there's no traffic because of a road closure further ahead. The UI when driving is not as good as the competition. I only use it because it has superior business listings with decent reviews and photos."

It's the same thing with Internet Explorer, they can get away with low quality and orders of magnitude prices increases and restrictions on the API because they can and they can because of the monopoly. Early decoupling could have allowed competition which might have had good data, more open or more fairly priced api, better UI and navigation since it could have made commercial sense to invest in these things.
