Because that specific post was in response to a comment about Eren being deadset on wanting to commit genocide only after the speech. There's nothing in the story that points to Eren only wanting genocide from that point forward. If that anon wants to ommit the entire part of the Manga where we finally get to hear Eren's thoughts and motivations he can make whatever head canon he likes, but as far as discussing the actual narrative the fact is that Eren was not looking at things from that perspective.
People want to cope Isayama changed and retconned the ending but he's on numerous occasions stated that he stuck to his original idea. I've pointed out an example of what Isayama was trying to do with Armin as the narrator and us as the viewer misunderstanding Eren. Even as far back as when Eren and co reach the ocean Isayama was laying the seeds of Armin and Eren having a different perspective on their dreams. Armin is happy, the ocean is as big and beautiful as he thought it was, Eren is somber because the WORLD isn't what he wanted it to be. I wont defend or disparage the choice to explore the narrative in this way but it's just a fact that's what Isayama was doing.
