I am not sure if I agree with the statement that Nokia's market share were destroyed by MS. If I recall Nokia was on its downfall even before Apple's iPhone came into market. I grew up with the 3330, so I always have a soft corner for them, it was my first phone and lasted forever. However, with the emergence of the iPhone, Nokia's fate was sealed. Most people here on HN including me considered Nokia DOA and it wasn't until the emergence of Lumia phones with its incredible Camera that people started to take notice. The comments went from "pfft DOA" to "I would totally consider if they made one in android!".
Strategically I think it was a better plan for Nokia to go with Windows regardless of the CEO. Apple doesn't do partnerships and the only other popular option was Android, which was ruled by Samsung and to compete against them would be to compete against a Goliath. So indirectly I think MS did help them even though it was for their own gains.
Also keep in mind, only the phone division was sold to MS. The rest of the company is intact and still trading in the stock market.
