The risk here has never gotten near a point of being about Sunbird slowing down iPhone sales by allowing iMessage on Android. Beeper already has been doing a workaround for sending iMessages from other platforms for a while.

The issue is Sunbird's shoddy implementation in particular compromising the security of a bunch of their users' accounts, with a real Android OEM vouching for their service and shipping it on their new phone, giving Sunbird a big publicity boost in the process.
