I don't think they really need to split. That'd duplicate resources to some extent, I think. They already fight internally and act like separate competing companies anyways instead of making a better software product everyone benefits from with a common vision. This recent post on Cult of Mac shows this quite well: http://www.cultofmac.com/apple-ms-google-etc-imagined-as-fun-org-charts/102917?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+cultofmac%2FbFow+(Cult+of+Mac)

The default shred command in knoppix is better than dd if=/dev/zero of=/dev/hda in my opinion. To start, shred will show you progress and what it's overwriting the data with (random, zeros, etc). Second, you can specify the number of times it rewrites the data. All formatting is also erased.

Simply enter the following command:

sudo shred -n 2 -z -v /dev/hda

This shred command will overwrite the drive twice (-n 2). Random data to start (defalut), zeros to finish (-z). The -v tells you the progress on the drive.
