Toasty as posted elsewhere here is the lead devs position on GPLv3:
[...] given up on anything but permissive licenses and will primarily support and contribute to projects with permissive licenses.
Bad actors violate the licenses anyway and it gets in the way of using it via license incompatibilities and other painful restrictions.
Any permissively licensed project can't take GPL code because it would change their overall license to a restrictive one.
GrapheneOS has a strict policy against integrating GPLv3 code because it prevents building things we want people to be able to build with our software.
I also note the lead dev stating in the issue tracker:
We also aren't even going to consider giving privileged permissions to a third party app.
My response above also reiterated this:
MetropleX As has also been referenced is that the project will never advise or advocate the use of/implementation of third party privileged services whether that be through breaking/bypassing the android security model or including them in the OS.
