From that 5% market share they capture approximately 45% of the profits.

That number is nonsense. If you follow the source, it comes from Dediu, who's a well known Apple apologist, and if you read his own article, there's no substance to it.

I'd love it if we could find actual, objective numbers.

To be honest I don't really know much about Dediu but I did read his article and I didn't get the impression that it lacked substance.

What is wrong with his methodology or assumptions that invalidate the 45% number?

I am honestly curious because I don't want to continue to cite a bad source.
