Microsoft.Taints.Everything.
It buys things in order to bring them under its authoritative control.
The company's ability to gain authority through authorship/creation of useful things is actually more limited than you might suspect.
This goes back back to the Microsoft's earliest history if anyone has ever read about it.
Microsoft is however very skilled at putting systems in place to eastablish consistent monetary streams for itself.
[It should definitely be paid XBox live account or ads not both]
It is a masterfully manipulative business. When you, as a customer, gets locked into Microsoft, lie in the bed you made.
And no, I no longer run Windows except in a Virtual Machine when it is absolutely necessary because of someone else's lack of foresight.
(Hint to web designers: don't require Windows specific technologies to view websites.
It entirely counters the interoperability goals of the internet. Use equaivalent open standards).
/End soapbox.
