This was always coming and the main reason I found it difficult to recommend 360.
Interesting that the first thing on the chopping block is the ability to move to another platform - cunning stunt indeed.
Sadly, Rhino, FreeCAD etc don't offer the CAM capabilities and anything else that does is going to cost you big time, particularly if you start moving into 4 and 5 axis land.
Dunno how this one will play out.
