Maybe it is me, but I'm not sure I understand this note so I will try to

We will release the source code. This is good and welcome news. And I assume the
part not released is not essential to compile or can be readily reconstructed.

As several

But it will not be free or in the public domain.

Also I assume that changes may take place so that the old free source would become

Wait, we can get free source code from Cornell. Good.

U can get a commercial license from one selected source organization, not Cornell.
And u need this if u want to do commercial development of derived products.

I'm not sure what this means.

Ok I undertsand this ....

Wait, I can get the executable free from Cornell or get the source and compile it.
Does this mean that only if I am doing commercial work has anything changed?

This is a very nice idea , I assume that will help us handle strange capture cards, etc.

I know this seems cynical but I guess I don't get it. It seems as tho non-commercial
users can get free executable and/or source from Cornell. And if we wanted a more
bullet-proof executable then we can get that from the commercial licensee or bid on it
ourselves and become the commercial licensee??? So I guess I don't see what the
controversy is?
