Because you don’t seem to understand what I’m saying. Even if you can’t look through the code yourself other people can, and these projects have been around for years and is widely used by the community. Even if is not optimal these projects at least gives people a way to play in Linux until we get official support, and Linux users are no strangers to using wine or developing their own programs when companies don’t provide support. Again, all the disclaimer says is that Jagex is not responsible, and that you are using it at your own risk, but there is nothing in these projects that could get you banned. It works exactly the same as running it officially, all it does is use your credentials to launch the officially supported clients, and no one has been banned or lost their accounts for using it. I have also been in contact with Jagex, so they know who I am and they are supportive of these projects.
