I have taken a look at random git repo that seemed important enough: https://android.googlesource.com/platform/system/core.git https://android.googlesource.com/platform/system/core.git There's about 5% of commits made by people with e-mail domain different than google.com, android.com or chromium.org (6% if you count the last one too). Pretty much the same result on another one: https://android.googlesource.com/platform/frameworks/base.git https://android.googlesource.com/platform/frameworks/base.gi... Do you get to see the code of yet unreleased versions of Android? Sure, they do accept some patches, but "developed in the open" doesn't seem to describe their development model.
