Citing your sources is not incompatible with the GFDL!
No its not, but releasing the sources on the precondition that the work is so cited in perpetuity remain most certainly is (unless they're in an invariant section) for the same reasons BSDL + advertising clause isn't GPL compatible.
The agreement is between Wikipedia and Euobserver, not between Euobserver and any users of Wikipedia's material. We shall make an honest effort to have the sources cited, for as long as they point to existing pages.
