Those people are now under MS management (or soon will be) and that management has proven itself severely incompetent where it comes to Windows Phone as well as several other areas.
While true, we likely disagree on the significance of that. These people are still geographically separate from Redmond, Elop is still their boss, and there is a chance Elop will soon run all of MS. Even if Elop isn't named CEO, the difference is basically one single person placed above him. One single person does not a corporate culture make, not to mention that negatively influencing Nokia's corporate culture across the Atlantic isn't going to happen, at least not in any way that matters.
If MS were to significantly reduce funding for Nokia's ex devices and services division, then I'll change my mind and adopt your position, but from what I've read that isn't the idea. MS really is taking the whole "shebang" under their wing and leaving the existing management structure almost completely in tact. IMHO that is what really matters.
Motorola has closed down operations in several countries after Google's Acquisitions.Now they operate very differently with a new strategy.
So NO , even if same people work , Management will still be different and they operate with complete control from higher MS authority.
If by "management" you mean that one single person will be added to the top of the organizational chart, then yes, that will be different (see above my opinion on how important that is). However, we don't really yet know how this will turn out. Elop himself might succeed Balmer as CEO, in which case there would be almost zero difference compared to Nokia today.
Nokia and Microsoft already work very closely. They had already aligned their roadmaps and strategies (MS had to be convinced that attacking the low-end is the better approach than trying to out-Apple iOS at the high end). MS gets that now. Nokia was already by far the most successful WP OEM and Microsoft will want to push their strategy forward even harder. This is not even remotely similar to the position of Motorola when it was acquired by Google.
