And they aren’t (for now) changing the license of future work either - just not releasing source until the same time they release binaries, which is totally allowed in the open source licenses.
They could close everything except the kernel and maybe a few libraries here and there. The Linux kernel alone does not exactly get you close to having an Android distribution.
They cannot take back the open license code. Only the future work is closed.

I.E. they would have to change the license of Android. Not sure how they are going to do that when the Linux kernel is GPL
