If an app developer chooses to devote their resources into certain platforms I can understand which would include not devoting resources into platforms that won't pay off.
Imagine if his same logic is applied to software. Should Outlook be ported for both Apple, Linux, and any other OS out there simply because it's fair?
Here's a tip, if developers aren't adopting your platform it may be due to something besides neutrality. Could your business model suck? Could they perceive your platform as not having as large a user base?
Instead of crying that things should be made even look at your business model and business strategy.
Here's a novel thought, contact those developers on other platforms and ask them what your company could do to encourage them and possibly other developers to also develop on your platform.
If you ask me the "Crackberry" fad has entered winter.
