It will be interesting to see the uptake of the program given the many claims for where Makerbot has taken community designs and applied for patents. Last article I remembering seeing was quite recent (http://traverseda.wordpress.com/2014/05/23/makerbot-blatentl...)

This article does a great job of laying out the actual situation: http://boingboing.net/2014/05/30/whats-the-story-with-the-ma...

This article causes me to question my trust in BoingBoing and Cory Doctorow. The extruder is not the only open source component Makerbot is trying to patent, here's another one http://www.openbeamusa.com/blog/2014/5/22/stay-classy-makerb... Seems the open spirit of Makerbot has been run aground by their new corporate owner.

I still find it very strange that comments were so hard to make on that story. It seems almost like Boing Boing wasn't interested in a normal discussion.

Thanks for that link! Definitely a case (for me) where the news around the original outrage reached more than the truth.
