As has always been, every app must be ported to every specific device model as well as every major OS level. With BB10, this is even more challenging as the OS is totally different from before (though I've heard development is "easier" for BB10). Some developers choose not to port their apps to every device, other developers choose otherwise. But it's the developers who make that choice...so your question may be better placed toward them.
Occam's Razor nearly always applies when troubleshooting technology issues!
