That tutorial is not part of the Playground. It is part of the read-only official documentation in the Arduino website. I guarantee you that if it was in the Playground it would have been fixed years ago.
OK, so I don't keep up with all the little divisions. It's all Arduino to me. It's still broken and nobody seems to be concerned with fixing it. And I think that blocking off access to more areas just results in more stuff like this. Maybe if someone was taking care of things. But as long as something like this gets reported over and over and nobody can seem to come up with any idea on how it could be fixed then I'm not going to assume that things will be any better running any other part of the website in the same way.
Sure you may be on top of it now. But what happens when you get busy or move on.
