HP hasn't
given "people" permission to do that. They gave Dave Hicks
permission to do it.
I believe that they gave blanket permission for anyone to do
that.
Got any idea where/when that happened? From personal correspondence
with Dave Hicks, I know that he specifically requested and received
permission, but I have not heard of anyone else doing so, nor of any
blanket permission. If they have in fact done that, it would be quite
useful, but it doesn't seem like something that HP's lawyers would be
likely to do.
