From his conspiracy theory (I think he said in this video or the previous one), that the Samsung cup was already dominated by Chinese players, so maybe it would be too obvious (and potentially politically dangerous), if the remaining Korean player continuously got promoted through top 8, top 4 to champion all by win with forfeit. Also, the last one left in the top 8 was Shin jinseo, they might just have every confidence in him. And Samsung cup was the first one to adopt the new rule, so there will be no new rule to use before that, and there were players who got penalized for misplacing captures, and didn’t happen again and the penalty was not enough to flip the game (just saying according to the conspiracy framework, they tried but not enough, but this time is the very last chance to use it). I am not buying it actually, but I do think the referee was under some kind of political pressure from the corporations behind KBA, and their actions might not actually be for the benefit of the corporation, but the opposite, to scold them, like a mutual destruction to force them out of KBA (and the meeting of the next pro associations might actually be their “real battlefield”).
BTW, the new CWA announcement is out, so not a rumor anymore.
