He meant in contrast to "leading many to speculate that the invite would soon be rescinded". But why should we believe him without any quotes? "In reality..." oh okay, thanks.
"leading many to speculate that the invite would soon be rescinded" doesn't need quotes because it is a broad statement that can be observed. With people on these forums, Twitch chat, and Twitter saying things like "OGN on suicide watch", jokingly saying "x team deserves to go to Korea" because they beat NRG, and other such things, people were at the very least implying it should be rescinded. It's safe to say that if you think something should be the case, you're going to speculate that the very same thing might be the case, much like you're currently doing. It shouldn't matter if he has a direct source for this, what matters is if he has a source for Envy deciding to go, and he does, albeit anonymous. While anonymous sources aren't preferred, you have to respect your source if they want to be anonymous or else they'll never share this information again. Obviously this source can be trusted, as within 24 hours Envy tweeted they were going to participate in season 3. The fact that he references the source and doesn't directly quote them doesn't make a difference because a quote can be fabricated as easily as a source. The only thing harsha claimed to be factually true was that Envy is going to Korea, the rest is background and presumptions, which should be clear to an informed and critically thinking reader.
You're saying that Envy can't just accept an invite they've already declined because it goes against your values and how you believe invites should work. OGN doesn't have to share those values and follow that line of thinking. By Korean standards, finishing top 8 in APEX makes a team qualified for the next one, which Envy has done twice and NRG failed to do their only time attending APEX. You're fighting the writing and article as a whole because you don't agree with the contents of it, and it's a losing battle.
