If you were ARM's competitors, and or otherwise wanted to see ARM weakened to open up supposed market opportunities, one of the best ways to do it would be to form a consortium ownership, in which ARM will suffocate. The added bureaucracy and distractions will damage ARM, it stands zero chance of coming back out of that arrangement as good of a company as it was going in (the group will endlessly bicker, as it erodes operationally they'll begin discussing changing the ownership arrangement, as some of the owners will want it to actually succeed - that move will come too late to matter much).
