Hmmm...how a commercial software (that means i get paid for give it)
it will be consider "free software" ?
I ask because i surely do not understand correctly the GPL lisence and
all that stuff.

Good point! I got it because at the last portion of my email, i asked
for it. I asked them that:
"And in  the case i want to build something that i want to later sell
(as an individual)..."

so i got it back.

As i said, i do not fully understand all this license stuff. All i
want to ask is, i can make GPL software and gain money from this ? And
if that so, then why they "force" you to buy the commercial lisence in
such case ?
