This is a completely unstudied interpretation of the law.

Copyright law forbids nothing but establishes property rights.

Nothing stops you from putting software out there, which if it's free to download is considered an implicit right to redistribute.

Unless someone complains, there is no enforcement.

However, you retain copyright unless you give it away (incl putting the work into the public domain).

But that's not hard to do at all. State that the work is in the public domain and it effectively is if you are the copyright holder.
