The spreadsheets that I built which served as our team's source of intelligence were effective because of their design, not because of the custodianship of entering tidbits of information. To share the links would simply be to invite others to copy the spreadsheet for their own use next war and lose the advantage entirely. Actually I have little problem doing so and considered it ... I was mostly 50-50 on it. I asked my teammates and they all deferred to me. I decided against it simply because, as I said, the work is in the design and undoubtedly the spreadsheet would just be copied and used by others next time. I figured anyone who asked me by PM I would send a link to, and that most folks wouldn't be too interested anyway.
I could easily be convinced with any level of polite asking to share the document with fellow war members but -- obviously -- am not prone to feelings of sharing when people want to lecture me about sportsmanship because I'd rather keep my hard work my own. I'm sure you meant no offense by it but it's quite rude.
p.s. There are two other teams who have hidden their intelligence docs from the community as well and I think the decision is quite normal.
