What does bluetooth mean to Apple?

There are a bunch of bluetooth file transfer apps in the App Store. All of them scan to pair with iPhones, iPods, and iPads ONLY. They will not pair with Macs nor Androids. The first bluetooth app I installed immediately paired with a Mac using standard bluetooth pairing protocols. Seeing the same scanning popups in all the iPhone apps leads me to believe this is an iOS or device limitation, and not due to developer code. Does Apple consider bluetooth as unworthy as Java? Is Apple using their Goliath status to favor mobileMe/iCloud?
