It realy goes back to the strategy of vendor lock in, Microsoft just can't pull it off like they used to because open source is so readily available and more viable than it's ever been.
The Fear, Uncertainty, and Doubt propogated by Microsoft spans generations, and also can't make as strong a case as it used to because people know that there are alrternatives available.
Not so much about having a monooly on the desktop or bundling a browser, so much as it was about trying to leverage that to alter standards and control the source such that other browsers can't render what was made for IE 6, other office suites can't quite display a .DOC file like Office can. It was about making it so that things couldn't interact or be compatable.
Nothing has changed, MS just can't sell their FUD like they used to, and there's enough good open source alternatives that trying to extend something to control it just makes users loose interest. What's really sad is they still try to use this strategy even though it will no longer work, and this is why windows phone can gain no traction.
Best thing to do is use opensource, and let MS continue their downward decline into insignificance.
