When I was helping with the template, I wasn't thinking about authorship or anything like that. I just wanted to genuinely improve the template and contribute something to enhance the game. I understand that you put a lot of effort into the result, but it feels like the whole situation is due to resentment and a quarrel, and it's not worth it, in my opinion. The template doesn't belong to anyone, and anyone can use it. Everyone has the opportunity to play the version they like. And if a specific version is required for a tournament, then that's how it should be.
P.S. I think that if you're doing something like template creation, it should be seen as a hobby, not a job. If it brings in income, that's great, but after that, you shouldn't start treating it like a job and demanding something.
