Not supporting updates?
Chances are 75% of the Andriod phones in use don't either. All that removing them from the market does is give people the choice, pay more or take your chances on the likes of eBay, where it may be knackered or stolen.
Rather than the likes of MM stop selling them, just say its no longer supported.
