Assuming your assessment is reasonable, is this a situation where McNeel perceived the ratio of abusers to honest users of multiple machines became too high to be ignored? Another situation where the few bad apples ruin it for the rest of us? Certainly McNeel isn’t so naive as to think there would not be any dishonest users; I always assumed they just wrote them off to marketing promotion and goodwill.
In my case all my modeling is done on offline machines (mainly one). Apparently if I want to own two offline machines with Rhino installed I will now need two Rhino licenses, effectively doubling my Rhino cost for no change in the operating convenience I have enjoyed for several decades.
Hopefully your ongoing consideration of these policy changes can come up with something better for users like me.
