Nokia did not exactly embrace Free Software. Sure, the company contributed to a bunch of projects and obviously funded the development of the projects acquired from Trolltech (although they managed to gut the revenue-generating opportunities of that division - something which was either incompetence or an internal power play to limit that division's influence), but you just have to look at the interactions between the company and the community to see that the decision-makers didn't really understand how to work in an open environment.
The article makes it pretty clear that not only does Nokia reserve the position of power for itself in any initiative - the attitude was always that customers and the community should count themselves lucky to have access to the toys - but that the organisation wastes a considerable amount of effort on undermining the usability of the eventual products: arbitrary limitations on functionality, contempt for purchasers of their devices, and so on. If people in the organisation were actually assigned to implement useful things instead of measures to keep the customer in check, maybe the resulting products would be competitive.
In fact, Nokia is a great example of not leveraging Free Software but instead attempting to constrain it. Sun also suffered from similar internal infighting, in its case leading to a generally incoherent Free Software strategy as various divisions presumably tried to turn the clock back to the proprietary glory days, in complete denial of the trajectory of the company and the industry.
