That's definitely not me. The point is that an effort should be made to make available the data to the fullest extent possible. I don't think it's unreasonable to expect anonymised data to be made available. If the data connot meaningfully be anonymised that might be a special case, but I find it hard to imagine a scenario like that, unless the study only involved a very small number of participants (which would also make it less valuable). Maybe there are such scenarios though, I'm not stating categorically that there aren't, just that it seems unlikely, and if there is I'd expect them to be a small minority.
