regarding
http://www.fractint.org/
(...)
If the intent of the license is "We could force
someone to pay for
distribution rights at some point and deny them those rights if they
don't pay up", it is not a free license. Free licenses include freedom
to use commercially.
(...)
Some of the authors of the software provide full contact addresses (e-mail
and snail), so I think CC-BY-SA tag applies; if you change it, use it, or
want work done on it, then remuneration by donation is *somewhat* optional,
and you cannot market the changes, because the people who provided the code
did not intend it for sale. If some major distributor picked it up, or
someone did a major overhaul to make it run under Windows proper, and then
sold it (I suspect that UltraFractal is along those lines, because it
contains a bug in the outside=atan view that was in a version of Fractint
before ver. 2003), then royalties would come due, and it would be
impractical to figure out who is owed how much. So, I am still thinking
CC-BY-SA, and at cost or less.
