iBooks is still an iOS only application; with no Mac version.

Yes, I whole-heartedly agree with you on this point, and Microsoft certainly has done things to work against the interests of others.

Out of the stuff I mentioned, only the Azure SDK and tools is specific to Azure. You don't need to be using Azure to use the others. Granted, Microsoft contributed to NodeJS project because they wanted to support NodeJS on Azure, but that doesn't mean you have to use Azure to be able to use Node on Windows.

The Microsoft developer tools division that have been making progress on the open source front. Granted, all the open source work they done is in their interest - but that's the same for any company contributing to open source. These are some examples I can think of right now:

* they have assisted the NodeJS project in implementing Windows support
* they have contributed 3 (maybe more) concepts/libraries to the jQuery community
* they lead a fully open source project called NuGet (.NET package manager)
* they host the source code for Azure tooling on GitHub, and accept pull requests
* they ship jQuery (and other open-source JavaScript libraries) in ASP.NET MVC
* they release the source code for ASP.NET MVC, and probably a few other libraries
