Please allow me to be cynical and see here no embarrassment whatsoever. They cashed on this for years and will surely find other ways (and have some already) to further cash on people. It's only one of the schemes which got foiled, and only for a while. Yes, I have zero trust and the presumption is of guilt.
Why respond in such a clown tone? Of course they did not do it for the fun of it but your narrative is highly suggestive that it was a huge cash cow. It was not, from what was reported on regarding GM is sounded like the effort was more hassle than its worth. Not sure if that will continue to be true but perhaps its too much bad PR for not really any gain.
Did they really "cash" in on it? When I saw the prior articles on GM it sounded like a very minor revenue stream that did not scratch their overall revenue from vehicle sales.
