Disclaimer: This is just, like, my opinion, man. Also, I won't be discussing whether MakerBot has done anything illegal or not; I'll only be explaining what I think is going on at the company.
Recently, the MakerBot Replicator 2 was announced as a closed-source device. This didn't really surprise me. In fact, I'm more surprised they didn't do this with the original Replicator. Yes, they're a company we've all come to know and love, but I've felt that for a while now that they've been becoming less and less relevant to the community of 3D printing tinkerers.
