My team at a non profit organization designed and developed a niche software product starting 2012. It was licensed under the MIT license until January 2022. Thereafter the license changed to a commercial license, since we weren’t able to continue development without any funding and no one was using or contributing to our souce code.
A state-funded organization decided to develop a visually exact copy of the software starting June 2022.
It is clear to me that any entity was allowed to do whatever they wanted with our software until January 2022.
Is the state-funded organization allowed to create an exact visual copy of the software after we changed the license before they started development? They did not use any part of our source code.
As stated in  the "look and feel" of a piece of software seems to be protected by copyright. The question is, if that is still the case if the software was published in the past using the MIT license?
