Not really. No one can force Apple to support something. It is like Microsoft being forced to support their applications on WINE.

If a significant number of users were using iTunes to sync 3rd party devices and a future update to iTunes inadvertently broke that syncing, who do you think the consumer would blame?

If a significant percentage of Microsoft Office purchases were run on WINE, Microsoft would be forced to support that scenario. However, that's not the case.

They would only be "forced" if Microsoft recognized revenue potential in WINE users, then it's a business decision.

So as a vendor what I should do is force my own customers not to force me to support their needs?
