I don't think that's a good parallel. Windows is an actual platform. Microsoft thrives on third-party software that runs on Windows. There are tons of things you can build on Windows without worrying about competition from Microsoft. Twitter is more like an app than a platform. Building little apps for Twitter is like writing features for MS Outlook. You can be bought by Twitter or MS but it's a risky proposition.
