I need to point out a few things to you. Firstly, Adobe made Audition 3 available freely until last year. The decision to withdraw it, and all other versions of almost any software apart from the current and -1 versions was not effectively made by Adobe - it was based on legal advice regarding something quite specific, and we are absolutely not allowed to discuss it. Secondly, if you can locate the software download and its serial number it will still work fine, and there's still help available for it here - but not the download. You have to locate that for yourself. So you are incorrect about the 'zero care' thing - we still offer user support here. I believe that you can still even download the 3.0.1 patch, if you look for it.
