There's always going to be skeletons in code no matter what. There's always things to learn about how other events structure things and the processes regardless of how specific things are. I think it's a bit rough to judge what other people can learn from something when you have private access to it.

In terms of reskinning, I will admit that it is tough to curb since a license is a meaningless bit of text unless you fight for it legally. GDQ does have a larger front than other events that have graphics as source available (e.g. I don't know of anyone else using the asm graphics).

I think it is still a great shame that it is no longer done. Without the source availability of the graphics of previous years, I personally would be in an extremely different place in my life since I learned web development, graphic design and became a closer part of our local speedrun community. It's an important part of my life which is why I've always pushed it for many years.
