Just want to point out that my explanation on the front page was intended to be as simple as possible for the general audience, obviously there are much more significant differences between manga and doujinshi.
One thing you can look forward to is multiple artists and circles on doujinshi, and including the tankoubon that an individual manga came from. Maybe even the event it was originally released at?
It's not that it's oversimplified. It's that it's wrong. Doujinshi can be original, or in the FAKKU definition, Manga. Manga can probably also use established series given appropriate permissions from the original creators, although I doubt it would be worth their while commercially in most cases.
Dividing into original and derivative works is a good idea. Using the words Manga and Doujinshi to label those is not. Those have specific meanings, even if a large portion of the hentai population isn't entirely clear on them. Those meanings have been explained sufficiently by others, so I won't go into it. FAKKU being so large, it will only help to propagate false definitions if this labelling goes through.
Label them as Original and Licensed Series, or something similar. I really don't recommend trying to repurpose existing words to mean something they don't.
