Re: Re-using copyrighted code

Show key headers only | View raw

I can't tell you as a lawyer, but I can tell you that regarding code
for non-commercial use, the only supportable case is requiring
fair-credit assignment.  If reading the original license (which you
are obligated to do if you re-use and re-distribute the code), it
stipulates that you must re-share accordingly, then you should,
otherwise there's very little case that could be brought about if the
code was put into a published, "open-source" project, whatever the
license.
