Or maybe they really have lost touch with what a webmaster really needs.
Google is more interested in collecting information from webmasters than it is in providing it to them. If that weren't so the data would not be outdated, inaccurate and incomplete to the extent it is.
As for the message, any changes that would please Google would not be detectable by the average visitor and so you should ignore Google and focus on the visitor.
Seriously - DO NOT WASTE YOUR TIME ON PARTIAL NON-DESCRIPT MESSAGES even from Google. They *could* provide you with a list of offending url's but they won't so why should you waste even ONE hour of your content creation time on them?
I would send in another reconsideration request that simply states "I've done what I can with the information you've provided me and I consider this matter resolved. If you do not think it is resolved please send me a list of the offending urls you have found, otherwise I'm wasting my time chasing content on websites I do not own or know about and your generic message will have been most unhelpful. Thank you." (but don't send it until you HAVE done all you can).
Also serious, if Google 'detects' unnatural anything why can they not share a url and save you hours of guessing? It's ridiculous.
