Three things:
1) That describes a corporate goal, not a set of behaviors used to achieve it. There are many companies out there who also have the goal of "Keep everyone using our software.". Not many of them have utilized such destructive techniques as Microsoft has in pursuit of that goal.
2) Your second sentence would be more correctly spelt "Microsoft's game plan is to keep everyone using Microsoft software, wherever possible.". When you spell it that way, it becomes clear that the big picture actually hasn't changed. Windows was (and remains) a big part of that game plan, but for the past decade or two, it would be hard for an honest observer to make the claim that Microsoft was only interested in keeping folks on Windows.
3) Many of us have seen Microsoft play nice with the wider community. They never play nice for very long. The more cynical old-timers would say that this "play nice" phase is -itself- a part of the EEE strategy.
