I don't think he was insinuating that he believes we're all in jeapardy of winding up in the burn unit down at our local hospitals. I believe he was more or less just sighting possilbe excuses someone at Motorola might give if asked why they're locking down the bootloaders so tight.
I will give 'the masses' credit though, there are some honest to goodness idiots out there. And like what I think he was pointing out is, it only takes one idiot doing something completely absurd, and filing a lawsuit afterwards to cause a company all kinds of grief. Companies really don't have any choice but to protect themselves against shit that they really shouldn't have to protect themselves against. If you've ever read a, "Stupid Lawsuits" book of any sort you know what I'm talking about. Some people go out of their way to missuse a product in a way so that they get injured just so that they can sue the company and live on easy street.
The biggest problem is that the courts have awarded so many of these people victories when anyone with any sense of logic at all can see that it should never have gone to court in the first place. Like the guy who sucessfully sued the lawnmower company after he chopped his fingers off when he tried to pick the lawnmower up to trim his bushes with it. If I were the judge of that case I would have told the guy, "we shouldn't be giving you ten million dollars, we should be permanently removing your from the gene pool so you can't breed any more idiots that don't know any better than picking up a running lawnmower".
While I don't agree with locking down our phones, I do acknowledge that companies unfortunately have to cover their own asses against some really ridiculous lawsuits that have been waged against them.
