This is all deeply disturbing, and perhaps even more so that so few voices are raised outside of the groupthink. I don't mean to sound unkind, but I really am disgusted.
GFDL is a strong copyleft license: fully viral (any work including work under the GFDL must be GFDL), and fully free (rinse, lather, repeat).
If the issue is invariant sections, why not just make a minor change to the license saying that if a document starts without them, it shall remain without them?
If the issue is the 7 pages of ugly license attached to works you are selling (that other people actually wrote), just print it on pretty paper. Infuse it with perfume. Put it on microfilm. Whatever.
I don't imagine my wife would be too happy if I converted to some odd religion tomorrow and let her know that she's going to have a few sister wives next week. Changing the rules in the middle of the game -- even if a bunch of you think it's a peachy idea -- is disrespectful, shameful, and completely discrediting to the idea of contributing free content with the confidence of knowing your content will always be free like you intended it to be.
I'm afraid I'm with Greg here: please make sure that those of us who disagree with this have the opportunity to remove our contributions, as well as all derivatives of our contributions. I'm not saying I'd do it, but I deserve the option. So does anyone who contributes and cares about how their contributions affect the world.
