I think it's more "I've created a way to make your Github contributions into a poster." I understand where you are coming from, but it's a tad bit reactionary, don't you think?

If I created a website for you to turn a user's facebook activity statistics into a T-Shirt I would hope that you don't think it is contributing to facebook's monopolism of social media.

Maybe a way to also include Bitbucket statistics (or something) would be nice. I don't know. Sorry, I might indeed have been quite harsh.
