All you have to do is google "Makerbot goes closed source" and you will find everything you need to know about them. I'm not making this up. Bre Pettis used to get paid to lecture on the merits of open-source. He was called the "poster boy of open source" by the press. It was a true slap in the face to the community. Of course, $400M will make you turn a blind eye and deaf ear to anybody and your supposed ideals I guess. The terms of use on thingiverse were change to state the following: You agree to irrevocably waive (and cause to be waived) any claims and assertions of moral rights or attribution with respect to your User Contentis This and other verbage was added just prior to their sale. In order to convince Stratosys to purchase them they had to prove that they were closed source. Many users took down their designs when this happened and replace them with "Occupy Thingiverse" logos. You don't see them much any more but they are still there. It's funny, but it has been less than a year since the buyout/sellout. Seems longer.
