Risker: it seems to me that there are two two different issues.

First, fear of criticism or controversy are not justifications for withholding information.

That said, I tend to agree you about the privacy issue for applicants. Any information releases should be compliant with what applicants were told at the time that they applied, and perhaps in future years there can be more specific considerations of what kinds of information should be released. Perhaps not much information will be released this year if users weren't told that the fact that they applied would be published (and my guess is that they weren't), but perhaps in future years this can be done along with other information that is not particularly sensitive, e.g. public contribution histories and public roles such as board or committee memberships.

(Note: I have not applied for a Wikimania scholarship and I don't plan to do so in the foreseeable future.)
