I think they have a better plan: Drive them away and then attract them back where and when needed. It's easier to launch a campain on a good, finished product that keep them through.

They attracted them before for Symbian, they can do it again.

Besides, why keep them interested? Meego is another animal, with a life of its own (if it lives), and is likely to benefit more from low-res adapted software from notebooks than ports from Maemo.

As for WP, it's better to attract Windows developer than pull Linux developers.

After all, all good platform have their large developer base. If you build it, they will come. I see no economical incentive for Nokia to hang on to Maemo devels. Especially considering the cost.
