Re: It's BeOS, it's the OS
I'm not batting for Google but I don't agree. Seeing as I've been using AOSP on my phones for several years, don't use Chrome, except for testing and have never used GMail. I think Google's use open source is interesting. There is certainly an argument to be had for the secret source approach, which is certainly true with Android and with stuff in the data centres. But Google does release stuff to the world early and does, in my experience, generally engage with developers more seriously than other companies do. I think they understand that making some stuff free and open source can effectively stifle the competition while suiting the service-based model. It can also encourage adoptive addiction (TensorFlow).
But they do engage constructively in a large number of projects. Even with the current shitstorm about Chrome extensions, their stewardship of Chromium is far more open than, say, Oracle's of Java. Their work on WHATWG and things like Polymer have definitely improved things for web developers and users. As has their work on video codecs (for which of course Widevine is the locked down, secret source). Enlightened self-interest runs through all of this but doesn't mean the projects aren't interesting or useful or always require their permission. And their is merit in this OS.
