If you also read posts daeken is more working towards loading linux than a homebrew launcher. He said specificially somewhere he wants one of those two, but more hopeful for linux. And once that happens he is leaving.
Actually as someone who both pirates and pays for games, I can assure you most games I pirate I would have never purchased anyway. Most pirates are either too poor to afford tons of games at $40+, or they can afford games and pay for most the ones they do care about, but also pirate games they don't super care about but still want to try out.
I would say you are wrong. They may pay for more games without piracy, but probably not by any substantial amount like you seem to think.
