Your stance is very nice and good intended, but I don't think being attributed your work should be a problem at all in forming a good community. IMHO the ingredients are not necessarily extreme humbleness and having the most liberal licensing, instead actually good contents and just basic politeness / not thinking of oneself as a superior being, should be enough.

Probably something like the GNU Free Documentation License [1] could have been also perfectly fine. It would also prevent some shark from waiting until the text is complete and polished and then take the work of authors and contributors and sell it while passing it as their own. And that's quite a nice feature in my book (pun intended)

Whatever, I like the idea of making this the best possible resource for all things WebRTC :-)
