Ok, Bart is right.
Now however I have something positive in mind related to this issue.
I started to think of this :
You can at least provide an executable
No lainz, that would be a license violation. DeleD was published under GPL which requires source code to be available when an executable is delivered. At least the source must be provided on-demand if not directly with the executable.
Now Akira1364 follows the license rules as he does not deliver executables.
Akira1364, an idea for you: start to make business with DeleD. Maybe you had such an idea already.
It would make sense if you really have worked on the code and improved it as much as you say.
GPL allows business. The license authors even wrote a page about it to avoid misunderstandings:
https://www.gnu.org/philosophy/selling.htmlIf you sell the sources, the buyer is allowed to copy and distribute it forward for free if he wants, according to GPL. So you may be able to sell it only once.
On the other hand, if you put a low price (say 1 - 2 € or $), and make the payment process easy, many people could buy the code just to get an easy download link.
I for example would pay that to see your code.
Companies that make long term business with open sourced SW typically offer services and support for the product, and / or include commercial SW that connects somehow to it. You could do the same with DeleD.
