They are individual contributors atleast willing to
contribute in some
way to the free software movement. Images made with proprietary tools
must have got into
www.gnu.org.in by mistake, mostly because the site
administrators didn't have time to check with pdfinfo and similar
I dont consider this as a mistake. We never rejected a code because it
was written in Windows or Mac. They were contribution to us and we
accept(as long as what they created is free). At the same time we wont
use use nonfree tools for our work and encourge others not to. As i told
some have offered to make new versions based on free tools.
I dont have anything more to say on this. Lot of work going on.
