It would still be very different. If you contribute to google mapmaker, only google could use it. If you contribute to a non-share-alike OSM, anyone can use it.

  > If you contribute to a non-share-alike OSM, anyone can use it.. I want those who agree with the project's principals to use the dataset, not just anyone. OSM isn't just a collection of data, its open collaboration. Removing share-alike breaks the model of that collaboration.

  The main assumption in the article was that people who voluntarily create maps (like I did) only care how much people they reach with the product of their work. And if that would be the case I would have chosen google map maker because absolutely everybody uses google maps. Google maps does not have a free data api, but that is completely irrelevant for this argument since nobody 1) uses that anyway. 1) Only a negligible fraction of people using maps.
