True, GOS team has not quit, but we don’t know yet what the consequences will be. They have said hardware support going forward will take more time than it used to. We do not know how much time that will take. We don’t know what functionality might be lost in the process.
Just because GOS didn’t throw in the towel doesn’t mean that they won, or that the fight is even over. No one knows what roadblocks Google’s next steps will cause either.
Google has all but officially declared that they look at custom roms and anything other than Google’s official android to be akin to piracy and hacking (something similar to a mod-chip from the old playstation days). They are actively trying to start an arms race between their prevention tactics and the FOSS community’s way around those tactics (or win it before it starts), just like with adblockers.
I use mouse primarily. Though on a laptop, if I don’t have a mouse, I would much prefer a little red clit-mouse and as much keyboard shortcuts as I can over having to use a touch pad…
