Samsung White and Samsung Blue Rigged Hard

Did you see the emotions after they lost? No way that was planned.

The team that won was the heavy favorite of the match, so this was not really an upset or anything.

Also, a rigged match, really? What would Blue have to gain by throwing a match? It harms their reputation, stops their chance at taking home that trophy and price money that goes with the biggest tournament of the year. And for what? These are people who were top of their region, do you really thing that people to work that hard would just hand off the matches to a different team, but because they share a sponsor?

Even allowing that there could be any measure of validity to this, the way this was presented just reads like an excuse to yell at Riot.

That is a really stupid assumption to say the match was rigged, you obviously didn't even bother to think of details before typing this. Samsung would have NOTHING to gain if SSB won rather than SSW, one of their teams would be in finals regardless. Also you obviously didn't even look at the emotions after the game. This game was clearly not rigged. Please look at details before making assumptions like this.

Forgive me if i am missing something, but why would those games be rigged?

They were just sad that they were forced to throw the game

You really don't understand in esports in Korea. Throwing a game is THE biggest shame a profession can suffer in korea and if they're found to have intentionally thrown a game they lose their careers, it's not like EU where a pro gets banned from worlds for being a jackass and still gets to come back.
