It's a true statement; LD_PRELOAD cannot be used with statically linked binaries. You can "fiddle" in other ways, but not by using the LD_PRELOAD attack vector (although personally I wouldn't call it an "attack vector", although in some cases it could be where you can upload a malicious file and control the environment of another program somehow, or something along those lines).
