so if the BSDs are en par with preventive measures, why is OpenBSD (to 
my knowledge) the only one shipping ProPolice, which prevented 
basically any buffer overflow seen in the wild for some time now?
Why is OpenBSD the only one to have randomized library loading, 
rendering basicaly all exploits with fixed offsets unuseable?
Why is OpenBSD the only one to have W^X, keeping memory pages writeable 
_or_ executable, but not both, unless an application fixes us to (by 
respective mprotect calls)?
Where's the non-root, chrooted httpd, dhcpd, mopd, rbootd, afs, pppd etc 
on the other BSDs? The privilege seperated tcpdump? This list is not 
even remotely complete...
And, why's OpenBSd the only one that has systematically removed all 
uses of dangerous string handling functions like strcpy, strcat, 
sprintf etc?

so, claiming the difference is how vocal a project is is, in this case, 
just far off reality.
