Or alternatively perhaps someone can explain to me > why software should be any different to scientific equipment, cars, If a car gets you from A to B, in reasonable comfort, you probably don't care too much exactly how the car works and so you are unlikely to need the source code to prove it got you to B. You *know* it got you there - there is no uncertainty of that fact. > dishwashers... If the plates are clean, the power consumption is not too high, and it does not make too much noise, I doubt anyone cares. There is little point in having the source code for a dishwasher. > I cannot use an open source mass spectrometer, You have a point with the mass spectrometer. People should be more critical with a mass-spectrometer. Unlike the case of the car and dishwasher, it is not so obvious if the results are wrong. However, I suspect is is easier to detect problems with a mass spectrometer than with a result from Mathematica. Read the archives of sci.math.symbolic and you will find many examples where commercial computer algebra systems give incorrect results. One obvious problem, even if the source to Mathematica was available, is that few people would be able to make use of it. However, I suspect it would improve the quality of the software, as some people will be able to check it. Solaris has improved since Sun took it from a closed source system to an open-source one. They have stopped selling Solaris, but of course charge for support on it. Is it any wonder that the most trusted encryption techniques are open source? Connect to your bank to make transactions, and you will be using SSL, the source to which is open for all to see. It would never surprise me if more and more companies or governments insist on the source of software being available. Far too many people are concerned about the issues of closed source software, and this awareness is growing steadily (not just with mathematical software). However, I can't see too many companies or governments wanting the source for the dishwashers or cars they or their sub-contractors use.
