every single one of them firms had Windows Mobile or some form of mobile Linux on smartphones going in one way or the other.
Again, I ask ya, if simply having these firms on board is all that it took, how come the other versions of Mobile Linux and Windows Mobile couldn't take the world by storm like Android has?
Prove it. It is quite likely that CPUs made by Samsung ended up running WinMo, and phones of Samsung manufacture were sold with it. However, Samsung wasn't in a consortium whose mission was the advancement of WinMo. Microsoft had the sole role in that. Microsoft found phone manufacturers to carry WinMo of course.
Remember how Symbian blew up and took the majority of worldwide smartphone sales? A lot of these same players are in the Symbian Foundation. Of course, these days we see they've mostly abandoned it, with the major exception of Nokia.
