Fragmentation of Linux phones

OTOH, this is pretty standard in FOSS generally -- an area opens up, a bunch of different groups try to build what they think the best solution is ("let a thousand flowers bloom"), and then after a bit there's a die-back and people consolidate around one or a few projects. (Or, often, a second generation project comes along that cherry-picks the best parts from all the earlier innovator's experience, and ends up wiping them off the map.)

Very roughly, it's a process that tends to optimizes for the total quality of the final product, rather than time to market or efficient resource use along the way.
