I think this is correct.

Nokia managed to push Ericsson out of their dominant position because Nokia were more of a consumer products company, including consumer electronics. But because Nokia did phones as consumer electronics, they didn't think about them in terms of a platform and had a poor position to compete with smart phones. Their best bet would probably have been to make hardware that ran Android, and at the time I was a bit surprised that they didn't. Their hardware reputation was stellar.

Elop's and Microsoft's actions were still scummy, though from Nokia's perspective they sold a failing part of their business for billions. Microsoft of course continued to run the phone sales into the ground.
