Hi all,


I'm looking at various Open Source licences at the moment
for a College project, and I was curious about how Borland
did what they did with the Interbase/Firebird code - i.e.
released it and then closed sourced it again.


How come they could do that? Is any code developed by
Firebird developers susceptible to be "robbed" by
Embarcadero? Or anyone else?


Or was it, as the holders of the copyright, they could do
what they liked with their own code, but not with other
people's? Does this mean, for example, that Firefox (not
Firebird) code could be taken back by Netscape?


Any explations welcomed - TIA and rgs,



Paul...
