Sort of the relationship of Android with the Linux kernel, for me this is the same as publishing a GPLed patch to OpenSSH or something like that, this is immense disrespect towards the developer community of a project, which does have its culture.
FSF has done this as well by changing the license of their software from GPL2/LGPL2 to GPL3/LGPL3 and turning the GameSWF (released under public domain) into the GPLed Gnash.
