I personally feel that companies should be required to go one step further and be compelled to release their embedded keys and source code for any product that they no longer provide complete support for.
Sounds great, but it's something the abandonware[1] scene has been fighting for over the past 20 years, to no avail.
I think the difference here is that when it comes to embedded software, very expensive capital can be tied up, as is the case in the above video. Not many commercially available software packages cost >$10k and very few people are exposed to that risk. Meanwhile, there are hundreds of millions of cars in the US.
It'll probably take one generation to raise the issue (and find an example for enough people to care), another to debate, and finally a third to agree about the common sense solution.
