#1 Thanks for doing that interview it added people in a time when we were loosing them.
DJ Delorie is still involved in that gEDA and PCB (mainline) are still on his servers. As a sort of landlord to the project I think he wanted to avoid being a part of the fight between the two sides of the gEDA project (xorn and lepton eda) and the mainline of pcb. (pcb-rnd is on Igor2's server in Hungary and some 5 or 6 mirrors around the globe)
On the PCB-RND side he has been helpful when it came to answering questions about the code and on our migration of a lot of data from his server
http://www.gedasymbols.org to our
http://repo.hu/projects/edakrill/ He contributed the code used to render the symbols into images for edakrill but in all other capacities he is uninvolved to my knowledge. It is possible he (DJ) is contributing via back channels.
Only DJ can answer the question of why he is no longer contributing in other ways. If *you* (meaning just Dave) emailed him I believe he might explain it privately. There was a time when pcb-rnd looked like it might simply become "the new" pcb (mainline). Meaning Igor2 and the rest of us would take over the original project and follow their last release with our latest. At the time the mainline hadn't made a new release in years so it was on the edge of "bit rot" into oblivion. DJ was involved in the discussion but not actually on ether side as far as I could tell. What I am saying is that in the scheme of things he is a figure who people still respect and he tries to use that honorably.
On a related note Igor2 got into the history of the project and wrote to all the past developers he could find and made this
http://repo.hu/projects/pcb-history/It has as many release of the project as we could find and written histories from as many of the projects past developers as we could get. I believe all of those release will run on a modern linux build if you install the dependencies (motif/lesstif and etc) a few people have run them for fun.
