I love that Make The Cut responded to the lawsuit by partnering with a cutter that doesn't require silly proprietary cartridges (http://knkzing.make-the-cut.com/), however KNK Zing is advertised as "open source" when it doesn't appear to actually be open source in any way: http://knkusa.com/?shopp_product=knk-zing

I've noticed this trend among non-programmers of using "open source" incorrectly to describe anything that's not completely locked down.
