We get a ton of posts here on the forum related to stuff in the playground that is wrong, misleading, or even dangerous
I think that's a serious exaggeration. I'm always on the lookout for those sorts of posts and they're not very common.
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.
It's still broken and nobody seems to be concerned with fixing it.
Sure you may be on top of it now. But what happens when you get busy or move on.
You're concerned with fixing it. I'm concerned with fixing it. Grumpy_Mike is concerned with fixing it. That doesn't make a bit of difference because none of us have the power to edit it. Right now, at least there is a good bit of content we the Arduino community have the power to improve and update at will. If the Playground is made read-only, all that content moves more towards the situation with the ShiftOut tutorial.As long as it stays publicly-editable, the Playground is not about me. Even if I've moved on, anyone is free to do it.
OK, so I don't keep up with all the little divisions. It's all Arduino to me.
Maybe they have changed their mind based on what has been said here by their customers. But are too embarrassed to admit it....R
