Was always unclear to me whether DanA was truly pushed out, or if the board (largely comprised of GM execs) wanted to take the company in a different direction than Dan wanted to go, and Dan decided to leave rather than stick around. Ie. IPO vs keep it a majority owned subsidiary.

I got the impression that it was a conflict with Mary Barra specifically, not so much the board as a whole. They simply went along with her. The tone of the notice was indicative of being pushed out, not a mutual parting of ways.
