I hope that the perception you had of my answer is the result of my poor English writing, as it is far from reality.
Since I am used to writing code that is not easy to decipher for private projects, I would have to rewrite all the code to make it readable. This, as you can imagine, is a big job that I would not have to do if I did not want to make it open source.
Your question made me think that if I get DHF funding, it would make a lot of sense to make it available to others. But as I said, that's a lot of work, and the project isn't even finished yet, and there's still a lot of coding to do.
Thanks for your comments!
