On Aug. 24, KeSPA released a statement that they will participate the next GSL after GSL Season 4. In order to prevent another fallout of leagues as eSports Federation made a statement to boycott OSL, all teams in KeSPA decided to participate the next GSL tournament that will happen after GSL Season 4.
Here is the direct source for the article that OP provided, if anyone who speaks Korean fluently wants to clarify whether it states that they WILL or WON'T participate in GSL 5 please help us out here.
Problem here is that it doesn't say anything about season 5, just future gsls.(in dailygame article linked above, not the english one in OP, someone must have written it and inferred that future meant season 5) They can pull "oh sorry we are still busy doing that bigggggggggg project, maybe try again for next gsl?". Nothing has changed as of this very moment. If schedule is an issue, why not allow b teamers to play? really shitty move by kespa.
Yeah, clearly assuming the worst (and pretty much the most unreasonable) stuff is the way to go, why would anyone even consider that there might be at least some truth to words of KeSPA teams and that they were going to participate in the upcoming GSL all along. Nah, it's much more fun to create drama all over the place and pretend the kneejerk from eSF wasn't at all ridiculous, lolll.
And yeah, eSF should definitely stay out of this OSL anyway - after all, why would we the viewers want to see tournaments running smoothly and games between players that we are fans of! Preposterous!
Right now the prevailing opinion in the Korean community is "Don't fall for KeSPA's bull****, this is how the GOMTV Classic got wiped off the face of the planet; since they're not participating in this season's GSL, keep the Federation out of this season's Starleague".
Nobody trusts KeSPA over there, whether they are Brood War fans or StarCraft II fans.
Well GSL season 5 won't be until after this upcoming OSL (so not until November). If the ESF teams wanted to match the KeSPA decision, they should announce that they will keep out of this OSL, but participate in the next one.
