if 'open' wants to compete, it should do so by being better than 'closed'. The argument in the article tries to outlaw being 'closed'. No one stops anyone from making any 'open' system (OS or hardware or whatever) and why should anyone stop someone trying to make a 'closed' system. If someone wants to make a closed system and someone else wants to buy that, sure, by all means..
If "safe" wants to compete, it should do so by being more fun than "dangerous". No one stops anyone from making any "safe" system (automobile or recreational drug or whatever) and why should anyone stop someone from trying to make a "dangerous" system.
One of the best uses of law is to place limits, regulations and standards on what businesses are allowed to get away with.
