No they don’t. Some people genuinely hate notifications. I do, for example. That’s a valid reason for not liking Growl, configurability doesn’t figure into it.
If those who hate Growl were to claim that everyone should hate Growl they would certainly be wrong – but that’s a different point.
I think you missed parent's point. If you hate notifications, Growl is good because it lets you disable them all easily, instead of having to disable them in each application.
