Only the original copyright holder can decide what the license of wordle is. You cannot take their work and “make it open source”. Please do read up on how open source licensing and copyright works. You could create a repository of the code as-is and call it preservation if you’d like, that’s ok. The author can still ask you to take it sown though. But you cannot relicense it and tell people they can do whatever they want with the code. It’s not yours. The original author could have open sourced this but didn’t. You can’t just do it for them.
