Fartis says he isn't sharing his code, but everyone keeps saying it sucks... sounds like a paradox to me^^
and I've never had a problem with his servers. My server runs steadily, I regularly play matches there (highly competitive 5on5s, these kinds of matches demand the highest quality of servers).
My server is also preferred by many international (EU) players, because it gives usually a better ping than other servers.
and yea 2 Euros and free is a big difference. With 2 Euros I have to set up some kind of payment options (paypal, credit card, bank transaction, whatever), I have to make sure the money gets transferred in time every month etc.
So I really enjoy that I just had to register and go rock on my server
