I wonder what kind of car Stallman drives. Seriously. Does he update the firmware controlling the engine timing and fuel injectors?
What's that? The car manufacturers have digitally handcuffed him so that he can't go mucking around with things? Oh - it must be a safety issue. OK, well, surely he can update the firmware for other things in his car, such as the radio display?
People aren't hearded in to giving up their freedoms. There are certain freedoms that those people just don't *need* to begin with. My mother, who has an iPhone, isn't handcuffed - if anything, the device liberates her into using technology that she wouldn't otherwise use in in the modern world.
There are products across the spectrum that address the balance between usable and the freedom to do whatever you'd like. Just because manufacturers lock down their devices doesn't mean there's not a suitable audience that doesn't benefit...
