Thanks for pointing this out! We had quite a difficult time trying to figure out all the licensing options prior to launch. It was especially difficult because we were distributing both software (to convert the names/shortcodes to the appropriate emoji image file name) and the emoji artwork/fonts, which seemed to require different licensing structure. Someone wanting to use our conversion scripts on their website needed pretty different wording than someone wanting to use our emoji on t-shirts they wanted to sell, for instance.

We were fortunate enough to have a little guidance from one of Wordpress' general counsel on the different licensing options and how it would affect our ability to work with them down the road. We've sent another note to them just now to see if we are still looking okay in that regard, and we'll update things accordingly if changes are needed.
