I mean, you are sacrificing all of your possible margin on OS to a third party, so yes, while you may sell more phones in the short term(the warmth), soon enough there will be many many more competitors with nearly the same thing and you will be lost in a sea of cheap hardware with little to distinguish youself(the wet cold that comes after)
