[Php-it] php e GPL

[fabiogandola at tiscali.it]

Ciao a tutti,
se prendo degli script PHP rilasciati sotto licenza GPL2, li modifico 
e li uso sul mio sito, devo rilasciare i sorgenti modificati?

A riguardo, cercando sulle FAQ della GPL ho trovato questo pezzo che 
sembra interessante:

http://www.gnu.org/licenses/gpl-faq.html#TOCUnreleasedMods

A company is running a modified version of a GPL'ed program on a web 
site. Does the GPL say they must release their modified sources?
    The GPL permits anyone to make a modified version and use it 
without ever distributing it to others. What this company is doing is a 
special case of that. Therefore, the company does not have to release 
the modified sources.

    It is essential for people to have the freedom to make 
modifications and use them privately, without ever publishing those 
modifications. However, putting the program on a server machine for the 
public to talk to is hardly "private" use, so it would be legitimate to 
require release of the source code in that special case. We are 
thinking about doing something like this in GPL version 3, but we don't 
have precise wording in mind yet.

    In the mean time, you might want to use the Affero GPL for 
programs designed for network server use. 

Sembrerebbe che quindi con la GPL2 chi usa sul proprio sito degli 
script modificati, non è obbligato a rilasciare il sorgente 
modificato.. o sbaglio?

grazie
