This  is  always  a  tradeoff/balance  thing.

The protocol to talk to MPSSE is well known/open (they do praise 
developers of open alternatives on thier web site) ,
their driver and dll are distributed without restrictions but not with 
source code. So it is not GPL but at the same time it does not put any 
restrictions  on my code in OpenOCD.

What is the situation with the ZY1000, I assume that all modifications 
to the OpenOCD source tree are public, but can you guarantee that the 
code running on the Zylin1000 does not link to anything that is nonopen 
and thus violates the GPL ?
