Honestly they might not even mind never winning a LAN since they generally always make it far, so the prize money tends to be good, plus by making it to most internationals, they grow their fanbase (ends up growing their bundle sales). Also their playstyle is fun to watch but likely just not enough to win a tournament.
Im guessing the decision making of the owner is largely based on what the fanbase thinks and wants, for example switching out Monyet for Jinggg was likely partially inspired by fan reception of monyet at the time and Jingggs popularity.
Sucks for the fans who really want to see them win internationally but as an owner, honestly probably doesnt get much better than that. Also their operating costs probably arent as high as the costs of other orgs, since they have such a small coaching staff (apparently Alecks has 2 analysts that work part-time, dont think that costs much though).
