Last time Apple pushed a battery-related software update that avoided shutdowns (good), people had to sue them to get a compensation: https://en.wikipedia.org/wiki/Batterygate
You had to pick battery or strings attached cash, before the update arrived. And the battery replacement required you to send your phone off for repair leaving you without one, and Google didn't offer an sla for turn around.
And let's be honest, inconveniencing me is hardly acceptable, even if the company makes a token effort to put things back to before they inconvenienced me.
