This argument I'm sympathetic to. But I think it would sit a lot better with me if Apple were to produce an Android client. That it's a closed ecosystem doesn't bother me as much as that it's tied to their specific phone hardware.
(I'd still prefer to see 3rd party clients as I appreciate the integration those can bring. But the hardware lock-in is particularly egregious.)
