In October, when Steve Jobs publicly called Google's claims of openness "disingenuous", Android chief Andy Rubin responded with the first tweet of his life:
the definition of open: "mkdir android ; cd android ; repo init -u git://android.git.kernel.org/platform/manifest.git ; repo sync ; make"
In other words, Rubin says open means that you can use a command line to create a directory, download the Android source code, and build your own OS.
By that definition, Honeycomb is not open. Sometimes, Steve Jobs is exactly right. ®
