I've been expecting to see something like this ever since Gates started talking about spam. This license is an example of Microsoft's strategy for killing off free software as an alternative to Windows.

In the absence of resistance, Microsoft has a good chance of imposing whatever standards it likes. Let us, therefore, resist it here and now.
