Never say never, but I really don't think this could happen at all. It is merely some pump and dump analyst creating FUD. Just like the Samsung rumour was.
In the ridiculously off chance that it DID happen, I think Apple would use the patents and software to make their devices secure (because Good and MobileIron etc are not as secure), and carry on.
I doubt Apple would adopt a keyboard, nor manufacturing/designs either. In any case, Prem/Fairfax/Chen et al have stated publicly that they have no interest in selling.
And yes I know things change...
