Which init system for Debian?

Does it necessarily follow from Google's choice of bionic rather than glibc that that they "avoid it like the plague" for licensing reasons? Seems like there are technical reasons to use bionic rather than glibc in phone environments (it's much smaller, apparently works better at very low clock frequencies, etc.). Course, they *might* have chosen it because of the license, but it seems dangerous to assume political reasons for a technical choice, absent any citation.
