But that's
exactly the point.
If Android ends up on the majority of phones, but they end up being low end phones that produce little profit per phone and those profits are shared by a whole raft of manufacturers: HTC, Moto, ... does it
really matter to Apple that they make so many of them? That's not a market they (or their shareholders) want to be in.
This is why Apple is happy to have only ~8-10% of total US computer sales (sorry I don't have a link for this either, but believe it is about right, at least within a factor of two at best) but have the lions share of computers over $1000 (just google for "Apple computers over $1000" for a variety of links reporting 66-90% market share in this segment since ~late 2008).
FWIW your first link for 25% is for USA only. This is a global industry, so I think that is also a somewhat meaningless number.

Restricting the market down further just tends to make Apple's share of the profits larger.
