It's funny how they had to recall the CPUs (even if they tried to make it harder), and now, with all the security issues (from spectre to downfall), where the patches cause a massive CPU performance hit, noone is yelling for a recall.
The buy back option was based on pricing before the news broke and for a good condition vehicle, there was an adjustment for odometer miles, but the vehicle could be in any condition, just had to run and move on its own power. They were not permitted to resale purchased vehicles anywhere globally unless they were modified to properly comply with emissions controls.
And they were forced into selling EVs and building a charging network. Maybe that will work out for them, maybe not.
