I asked this a few years ago....
I think it's time to revisit this, as this reason has become a bit of a hobgoblin to this site.
It appears to me that the mere mention of a specific company or policy inspires a mass rush to close a question even if it is answerable or if the question and answers could apply to other companies.
I believe we should drop this as a close reason. Of all close reasons, this one seems to be rarely used as intended, and most often reversed.
