I wonder if we are being caught in the fallout of a discovery (or a belief) that too many small businesses were using the free version? The innocent are paying for the sins of the few!

It's still looking like the best free 3D cad tool out there (and I'm not anticipating the "open design" limit to affect me too much as I tend to have only a couple of projects on the go at a time and have a lot in each one - not a lot of separate component files) but the G0/M6 business is more concerning.
