Like GNU/Linux. No one cared.
Hate to break it to you, but we still don't care. Seriously. 99% of the people who use Android have no idea that it has anything to do with Linux. They just call it Android. And of the small minority of people who run "Linux" on the desktop, about 99% (from my observation), just call it "Linux." Richard Stallman and a handful of his groupies are still the only people who still care about putting "GNU" in front of Linux.
