The Irony being that it's for Open Source software...not their own.
Microsoft really needs to stop acting desperate and just making good software. Once their marketing machine can ratchet down the bullshit and just sell a solid reliable product instead of a complicated piece of software that has become synonmous with death (BSOD reference here).
If they REALLY want to make money (hope you are reading this Ballmer) They could easily make an OS based on Linux open source it keeping certain elements proprietary while still keeping with the GPL and release at a lower price point. They do something like that that allows existing compatibility with ALL Windows and Linux programs (can you imagine a debian-like OS with 100percent windows compatability) And no not like WINE, great project but still far from 100 percent compatibility.
They get the best of both worlds. They get the linux marketshare...and the anti-trust hawks off their back. Because people still have a choice. And if they do what is right by consumers while respecting their freedom of choice (creating a great product without the lame ass lockin), they will earn their name as a quality software provider.
As it is they create "tools" to find the openings in other products flaws, but seem to miss their own. They had a few thousand bugs still open from 2002 do they not?
