Automattic isn't unique, we just follow the same Open Source business models everyone else does. We do hosting, and provide extra services.

There are at least 1,000 plugins in the directory that do the same thing. There are plugins for Youtube, Adsense, Lijit, Flickr, Sharethis, Twitter, Paypal, translation systems, backup services, Statcounter, Facebook...

I'm not sure what that has to do with being GPL or not, or who exactly he claims I've mislead.
