Unfortunately the author has the facts wrong.. There were other android releases where the opensource commit was delayed for similar reasons, in this case its to port parts of Honeycomb back to the phone branch and once that is complete than honeycomb will be committed to kernel.org. Also note the opensource committers that work at OEMs do in fact have access..something author glossed over..as they commit code under the Apache License
