Seems very similar when Microsoft invested in Apple back in the day when Apple was about to die. Their concern was that they would be the only one OS company standing and be defacto a monopoly and regulated such. So, it was a away to keep your 'weak' competition alive just enough not to make you the sole provider.

Steve Jobs was able to turn around Apple in such a fashion that they become even bigger by letting go of the PC market and going mobile.
