The Google i18n font repo (https://github.com/googlei18n) went private all of a sudden in the last few weeks and it broke my Yocto build (and hey boot2Qt team, if you're listening, you're broken too).
I've been steadfast in not adopting any of the Google toy side-projects (e.g. Brillo, Weave, Things, etc etc) but now I'm expanding that rule to anything and everything from them at all, including AOSP. It's all quicksand.
