Agreed. But it is not only open-sourcing their own technology, it's earning money off of other open source technologies (which is perfectly legitimate). Want to run Linux? Pay Microsoft. Want to run Redis? Pay Microsoft. Want to run the next great open source project which I will invent tomorrow in my basement which will go on to be used by millions of users? Pay Microsoft. BTW it may sound like I'm being harsh on Microsoft but actually I think their strategy is brilliant. It legitimizes Open Source in every single way and shows the world that you can make money off of it - lots of money. Open Source developers should be rejoicing now that they have been vindicated after so many years of not being taken seriously and even being called "Communists".
