it certainly is not to say that the legal advice will be useless or have no weight, it is to say that it might not be as definitive as you are making it out to be.
Definitive, NO, you only have to look at say criminal law and see that if you get the right judge, the right defense team and a few technicalities that you can pretty much get off anything. Did someone say OJ.
What it would do is this, be a point of reference for anyone who wished to argue matters of Diku, or when someone wanted to push some extreme view thats not currently accepted as being the meaning of the license.. This alone will be pretty much and end to argument situation for the great majority. And while Eben Moglen himself wont reply to this email, i personally have enough faith in his team or students to provide credible and honest answers to the questions posed by samson.
Like all law advice you have to accept that the person dispensing that advice is being honest in how they interpret the laws at hand and then take it with a grain of salt when you set sued. All in all it still comes back on the individual to make the choice on what to do with that advice.
Its not like The Freedom Law Center is run by Linel Hutz Atourney at Law Thingy.
