Well there is a huge difference.
Chis simply decided no to sell it's product to certain customers.
I see no difference. Elbox simply threatens that if Hodges does not restore Poseidon stack registration for Spider, Elbox would decide not to sell (or give away) further versions of their drivers for certain customers (those who use the Poseidon stack with cards other than Spider USB).
Thats perfectly legal.
Maybe yes, maybe not. But for sure it is unfair for users and Elbox. Chris has not paid Elbox for writing Mediator USB drivers for his Poseidon stack. So Chris has some obligations towards Elbox. You can read about this
here. It is also unfair for users because Chris stopped selling Poseidon without any warning.
It's his product and he can decide whom he sells it too, weather you like it or not.
So you must give the same right to Elbox, because their drivers are their products and they can decide whom they sell them (or give away), right?
Elbox on the other side says "We will render our hardware ( that you allready have paid us for !!) useless if you also use Chis software."
As I understand you can still use current drivers. You have not paid for future drivers, right?
