"I had to make four new movies and slowly release them over several years in order to ask people to move on" seems like a self-defeating proposition.
Best way to make the audience move on from Evangelion would have been to leave things alone, so this renewed effort seems counter-productive to that goal.
In any case, I'm not going to take the word of image board posters too literally or seriously when it comes to media interpretations, so I'll see the film sooner or later.
Look at Gundam, in 1987 Tomino ended all Gundam storylines with Char's Counterattack, The Zeon were gone all members are either dead or abandoned the war to save the earth, in 1991 Tomino made Gundam F91 which was set decades after CCA and had the Zeon replaced with Cosmo Babylonia with the Earth Federation taking a back seat, in 1993 Tomino made Victory Gundam, once again it was set decades after Gundam F91, and the new villains are the Zanscare Empire, and the Earth Federation has all but been replaced with the League Militaire, the fact that its still set in Universal Century Gundam barely matters.
Then in 1994 Bandai buys Sunrise and plans to make Alternate Universe, when the first director Yasuhiro Imagawa asked Tomino what to do, Tomino told him that a copy of a copy will eventually fade until its nothing. Meaning that Imagawa had to show the Gundam fandom something new, so Imagawa created G Gundam, a comedic Super Robot show that still had some thematic connections to previous Gundam, but looked nothing like any previous Gundam.
The problem is that the fandom still demanded more of the same, they demanded the Earth Federation vs the Zeon, so Sunrise created OVAs that were set either during the One Year War or around the One Year War for those fans.
In 1999 Tomino created Turn A Gundam, a Gundam show that like the earlier G Gundam looked nothing like previous Gundam shows. It instead took place in an America that looked like something out of the 1920s. The mecha designs were either mobile Suits from previous series or were mecha created by Syd Mead who had radically different sensibilities from the Japanese mecha designers previously used. Most importantly Turn A Gundam was set hundreds if not thousands of years after any UC Gundam show.
The problem is that despite all of Tomino's efforts the Gundam fandom still wanted the same thing they got over a decade ago. The series that succeed were rehashes of previous Gundams. Gundam Seed and Gundam Seed Destiny are basically remakes of Mobile Suit Gundam, and Z Gundam, Gundam 00 rehashes Zeta Gundam in the second half.
Finally Sunrise gave into fans demand and made a sequel to Char's Counterattack called Gundam Unicorn, and it was basically the same thing as Char's Counterattack, despite being a direct sequel to Char's Counterattack, Gundam Unicorn has the exact same themes. It said nothing new. It was the copies faded to nothing, and it was a massive success.
Sunrise announced more sequels revealing that they planned to make shows that covered pretty much the entire era of Universal Century despite the fact that it defeated the very point of Gundam F91 and Victory Gundam being set decades after the Zeon Wars.
In one scene of Char's Counterattack, Lalah Sune is imagined as a bird, so in Gundam Narrative, the movie just never shuts up about birds. You are seeing constant imagery of birds despite the fact that it happened in one scene of Char's Counterattack.
Anno knows that Evangelion fans have an unhealthy relationship with Evangelion, he spent over a decade making that statement, but I doubt that this will be the end of Evangelion because Evangelion makes money, and Khara needs that money to make projects that they want to actually make. The difference between Tomino and Anno, is that Tomino lost control of Gundam decades ago, its now owned by Bandai Namco, a giant company that has entire divisions dedicated to milking Gundam.
Anno runs Khara who owns the rights to Evangelion, so unlike Tomino Anno benefits from milking Evangelion in any from while Tomino only benefits by having projects he wants to make have a Gundam named tacked on.
