From the article:
"One of the biggest problems with this approach, other than the fact they just pissed off a lot of people who beleive strongly in OSS, is that Growl is still broken. So you pay your $1.99 and it no workie. <samuel:jackson>TESTING MOTHER FUCKERS, DO YOU DO IT?</samuel:jackson>"
I happily paid for Growl from the App store, and sure enough it works fine on both my Lion Macs.
The 1.3 SDK also added Mist[0], which means software does not have to install Growl itself (and the user does not need Growl) to get Growl notifications.
The Growl application itself (from the AppStore) essentially becomes a "Growl Pro", offering users more (and centralized) control over notifications display.
