@ArneBab there is no reason for GNU to be part of the conversation about Linux or Android beyond those operating systems or distributions of them may choose to include some GNU software or software from BSD or anywhere else.
Announcing you’re making an OS and then not making one doesn’t give you any claim over the name of someone else’s project.
I haven’t had an Android device in years but I’m not surprised it hasn’t changed much.
GFDL should have been killed off much sooner.
