One has to sympathize with Bre Pettis, CEO of MakerBot. While he's had huge successes in the past few years, most recently by announcing the professional-targeted Replicator 2, he's also caught some flack from the open source community.

But we don't blame Bre personally for this. In fact, there is ample evidence that he supports open source principles and the concept of 3D printing for everyone. All you need to do is check out the list of projects he's supported on Kickstarter, some of which could even become direct competitors to MakerBot:
