Eagle, I dont believe its a criminal offence to break encryption, its merely a copyright violation which is a civil matter not a criminal one IIRC.

And its no different Simon doing that, to people like Stu or Tony or Karl doing it when they remap a car on standard management, as they are copying and altering the manufacturers data when they do so, which is no different legally to copying and altering their software as far as im aware, all of which are talked openly about on here, so I dont believe that is a problem either in terms of the rules despite how they appear to be worded there as until proof of copyright infringement is given (ie a civil case taken against one of them by ford or whoever) then the benefit of the doubt is given surely?

Stu's reasoning for not letting Simon (a known trader of ECU related products in the past) post openly about his developments on here was well document in previous discussions and is that he of course believes that doing so may be of direct or indirect commerical value to Simon, which isnt fair on other traders who have to pay if they wish to use this site for commercial gains such as product exposure which he would be gaining for free.
Simon got Stu on side when he said he would release under GNU, which would stop the product from being as commerically valuable to Simon as it would be opening the work up to others fully as well, but then Simon backed out of that part of the deal and so Stu said if Simon was going to want to keep commerical control of his product and as such have the potential to make money from it at a later date then he needed to be treated once more as a trader on here, which seems perfectly fair to me given the rules of the forum with regards to trading.
