I've removed every piece of security...
I can understand removing any signature scanners. We did that in 02 and, except for alpha/beta testing for friends/devs, we haven't had any onboard since.
FPs and faulty removal routines can and often do cripple innocent components. I think it is sad that so many still periodically rip the guts out of their system while usually using multiple scanners and without even a clue to what items they are removing. Then these same folks wonder why their system and applications fail to function properly after they have been ripped apart by various scanners.
However, even if you don't maintain any sensitive material or transfer, I can't understand why you wouldn't want to maintain control of your environment. Personally, I could not tolerate looking at the net without all the filtering in place. yuk
