I'm pretty sure this is referring to the operating profits on hardware sales, which would be a pretty silly factor in deciding what platform to write software for. Third party software devs make precisely none of that profit. Samsung also doesn't, afaik, make any of whatever Google's cut of Android software sales are, so even if it does include app store cuts that just turns it into an apples and oranges comparison.

This is not to say the conclusion is wrong, just that the data here is not relevant to it.
