Ok, so lets start from begining.
There is a open source gpl. I take the software and do some modifications.
I want distribute the code, everthing, but I wanna charge. Wich my options:
1. Change the license
R: I cant ok ?
2. I keep the gpl license but add a annex with new deffinitions. In this
deffinitions I add how I am charging and some restrictions.
The four lays of open source is respected, of course. But I add if the
software or some part is used
for commercial proposits I charge some $X for month or $XXX forever.
I can do that ?
3. If I have a open software gpl that charge $Y for commercial use. Can I do
a fork of this project that charge nothing ?
Thank you very much,
