Well the key difference here is, PostgreSQL (what Mammoth Replicator and
EnterpriseDB are based off of) is BSD licensed. To answer the specific
question, yes Mammoth PostgreSQL was closed source, it is more of an
auxilary FOSS project now. Mammoth Replicator is still closed source.

The BSD explicitly allows us to do as we wish with the code, including
fork, close source, mutate etc...

LedgerSMB is GPL, which is a whole different legal and ideological
mindset, although they are both FOSS.

I am sorry if I was unclear.  To me the key issue is permission.  To
take GPL'd code and make it proprietary, you need separate permission
(the kind Innobase/Oracle give to MySQL AB).  Mammoth PostgreSQL was
proprietary based on permission.  My concern with SQL-Ledger was that
it wasn't.

A lot of my past post falls under the category of "defend whoever
isn't in the room as much as is possible."  And that means Dieter.  I
wanted to clarify that the problem as I saw it was not that he
relicensed the code but rather that I did not think he likely had
permission to do so.  Despite the fact that I like the GPL v2, I am
not terribly political about it, and I think that authors have a moral
right to choose their own licenses provided that their obligations to
others are met.  The difference between Mammoth PostgreSQL and
SQL-Ledger was not in the mindset so much as the fact that Command
Prompt fulfilled their responsibilities to other authors while I did
not feel Dieter had (and it turned out that I was right).

Appologies for any confusion.
