Say I have a friend Don Drakulich who runs a small peep show empire and has bought a five hundred slot machines from a defunct Los Vegas Casino. Don Drakulich thinks of himself as and honest businessman, meaning he has free and clear title to these machines having bought them at an auction. And why he plans on repurposing them as adult video peep show consoles. They're perfect being based on slightly modified open source dev board running Linux. But however they have 'secure boot' so he can't modify the software so that they can legally be used in his peep show booths. But then again because his software developer has contacts with a board assembly house, he is able to get the secure boot processors replaced at a mere cost of $20 per unit or $10,000 for the lot. No big deal. So it sounds to me that secure boot has merely annoyed honset guys like Don. And not even slowed down the Serbian Mafia because they have a couple of their software guys working for a slot machine manufacturer. But you're made it hard for someone who casually comes into possession of a slot machine to re-purpose it as say a video jukebox. Also if anyone is still reading at this point I'll say this having worked on industrial controls that can both kill people or cause expensive damage to machines, equipment and product. The general trend is that the safety monitoring system must be separate from the command and control system. IE, the PLC can try to turn on the $100,000 vacuum pump when the oil level is too low, but the safety interlock won't let the pump turn on. That's the world I come out of and it's why I find all of the GPL-V3 will negative impact product safety arguements lacking. And why I can assure you that none of the people involved in those industries care about the GPL. And I'll say this, if you are primarily relying on a piece of software to prevent injury or death you really need to rethink what you are doing. For a good example of what can happen one can view this US Chemical Safety Board report on a accident that occurred at at facility involving controls that I personally worked on. http://www.chemsafety.gov/investigations/detail.aspx?SID=30 Matt Harper.
