I'm not talking about end users, those who will use the system, I don't think this forum is used by anyone who might potentially be interested in using a certain software.
I'm talking about the users of this forum, who are all developers, who might be interested if the source code were available
For two reasons: the first is to learn something new, the second is to be able to make the inevitable changes that any end user might request
I read the previous posts, where you wrote that "...is part of my life..."
I understand that, and that's why I didn't ask you to change your decisions
I wrote what I thought. In my case, I wouldn't purchase a project like this without having the sources, because I wouldn't be able to gain any benefit from it, neither in terms of improving my knowledge nor in terms of providing the system to an end customer (I wouldn't be able to modify or support it)
