It isn't Microsoft's job to write the damn apps, even though they did write a lot to start with themselves to get a good value proposition to start with.
And let's apply your flawed logic to other things:
"It's really ironic that Windows is being bailed out on its lack of apps by the web".
Doesn't work then does it?

The irony I was pointing out is that while at one time, Microsoft's Windows ecosystem had a huge advantage in number and quality of apps, now they are the ones relying on the web to fill in gaps where 3rd party software exists on other platforms but has not been written for their minority OS.
Sorry to have offended you.
What I'm saying is that the web transcends all platforms so writing an app isn't necessary. Microsoft actually do get this hence the focus on IE and Windows Azure recently. They probably have the best web offering on the cloudy space as well.
Microsoft do everything literally.
as for embrace, extend, extinguish, what you say is true but they got stuffed by the EU so had to start making open specification documents which are now available on MSDN so they have been defanged there.
