It caused people to think.
And maybe wonder what the band was doing. Being offensive is a goal in itself because it challenges preconceptions- much the same as Frank Zappa.

but other bands
Cause people to re-consider their view on the scene while still making more interesting things musically, think virus, or ulver, even fantomas. Who are much closer in comparison to what zappa was doing. In previous eras morbid or mayhem were the ones pushing sounds forward, I think offensive as your only goal is interesting but unsustainable, especially with someone as unstable as putnam at its head.
