Typically I've found that they ask first, however even that is annoying.
I don't want growl support, and I haven't wanted growl support in a very long time. I've yet to see a use case for it that didn't seem bent on interrupting the user with a distraction, and preventing them from getting things done.
Screw that, I'll stick with programs bouncing subtly in the dock, where I can ignore them.
(Not to mention, the last time I used growl it (or the programs who used it) suffered from a few bugs which would cause it to occasionally barf notifications all over my screen without warning. How rude!)
