@sharoz thanks for writing this up. So much in there that I recognize both from the reviewer and editor perspective... the delays bc of authors not responding, links not working, lack of documentation, results from the data just different from what the manuscript says...
I can't help thinking that we're seeing only the tip of the iceberg. When data and code sharing becomes the default it could melt away

@renebekkers The tip of the iceberg is exactly right. What's frustrating is that a neutral stance on transparency has the practical effect of disincentivizing it. If an open-data paper and a hidden-data paper both make the same glaring error, it's much more likely to be found in the open-data paper. The net result is a literature plagued with unfindable errors and a de facto discouragement of transparency.
