From the site, emphasis mine:
It's About the Message - No company logos on the front of your clothes (it's unbelievably lame that companies print their name on a shirt and call it fashion - and worse - people actually want to not only wear that shit, but pay for it). We "tag" our shirts only on the inside. AnarchTee invented the upside-down, inside bottom seam tag print. People love it, and can choose for themselves if they want to display the AnarchTee name or keep it to themselves and just convey a message with which they agree.
Nothing bad about it, it's just so ... American.
