My impression is that the original CircuitStudio was largely a Farnell Element 14 venture, perhaps they approached Altium to have it created. So, when Farnell lost interest in it, I was somewhat reticent to apportion blame to Altium. But in the case of CM Pro, that was wholly being pushed by Altium, so they are entirely to blame this time, no denying it. It's frankly stunningly poor business logic. I mean, if they played it right, and actually supported CS (CM Pro) properly, just a couple of updates a year, it really could boost future Altium sales. Instead, shoot self in foot. Crazy.
