There are quite a few things I don't agree with about the notion of collusion in the FGC.
1. Most fighting game players are not being paid to play. They are paying out of pocket to go to these things. Playing in the FGC is not a job. If I or anyone else choose to fuck around in a tournament, it's my business. I mean, what if a player decides (as happens a lot, especially with alcohol) to not play in a tournament? What if they stay and up party and then play like shit the next day? Should they be punished? Regardless of what anyone may think, these streams are NOT for the spectators; the spectators are NOT paying the players to play. If you're going to make the clause that every player 'play at their best', then you need to be paying those players to play. While you're at it, you might as well ban 'unwinnable' matchups and lowtier characters.
2. Fighting games are not like poker, where players can cheat against the table. True enough, a players can say, while, you'll probably beat *y*, so I'll send you to losers and then you play *y*, but, at that point, it's between y and z to play it out. These players are not rigging the brackets or anything like that.
3. In the particular case cited, the two players were brothers who were more than likely going to split the money regardless of who won. They said, 'If we get to grandfinals, we're going to have fun plays Izayoi mirrors'--that's THEIR CHOICE! With all of that understanding, you have to realize that THEY BEAT EVERYONE ELSE! Like I said, until people are actively paying everyone who competes and these players aren't paying to play, these tournaments ARE NOT SPECTATOR SPORTS and the players HAVE NO OBLIGATION TO THE PEOPLE WATCHING.
With that said, I can still understand that people want a show regardless of if players decide to split or not and I agree that it should be done for the good of the community. Still, unless the players shouldn't feel obligated to play a certain way unless they want to.
I should also note, for those who didn't know, that the TO only took the pot bonus that he had put in himself and gave it to third place. While I don't agree with that, it's understandable.
EDIT: I should note that, in case of poker, the players are cheating the table and probably wouldn't have won (have far less of a chance of winning) if it weren't for their cheating. In the FGC, you can 'collude' vs. one player but there's no guarantee that you'll beat the next.
