Looking at that, others can, and have, done worse than him and yet they don't get this kind of scourged earth treatment. I don't know who's grandma he ran over but from here it looks like WB just won't let go.
Given his track record with the people he's worked with and how down they are to working with him again, chances are that he helped someone's grandma cross the street and didn't run her over even once, but WB and their supporters still hate him because he showed them up. And let's be real: dude lifts. Dude's a damn chad. That grandma would've had a great time holding onto him. I'm just saying. Purported "breadtubers" are literally mad because he's physically fit and calling the fact that action stars have defined muscles "body fascism".
The Rolling Stone accuses him of being a Lex Luthor-type supervillain and vowing to "destroy [WB] on social media", even though he largely uses Vero and not Twitter, which doesn't indicate a strong social media presence by his own choosing. Tatiana Siegel, the author of that hit piece, was formerly at The Hollywood Reporter and had a rivalry with Kim Masters (respected journalist), and Siegel left because she couldn't successfully obstruct Masters's piece that exposed Joss Whedon and the toxic work environment Whedon fostered during JL. WarnerMedia is still trying to push the narrative that Snyder is some puppetmaster manipulating Ray Fisher to make his statements against their blatantly unprofessional conduct. WB even let slide how degenerates made (and probably continue to make) fun of Autumn Snyder's suicide, like she purposely did it because Zack's a "bad father"/made a bad movie.
WB emboldened the haters into believing they have full license to slap given undesirable political leanings on Snyder to paint him as a boogeyman who also "destroyed" their precious fictional characters. He "doesn't understand" them. He "ruined" them. They sit around sobbing on Twitter about "we gave him SUPERMAN!" because the natural state of human existence now is to treat corporate IP like an identity-defining religion and different interpretations are on the level of blasphemy. Superman is never allowed to have doubt because he must be the paternalistic arbiter of the status quo who tells people everything is okay and exercises his power in a way
they like, even if the people he
should be saving are being exploited every day in other ways or simply not cared about. They're so unimaginative that if Snyder existed with his takes 70 years ago, they'd have called him a
Communist, not a Right-Winger. He's whatever the current reactionary climate disagrees with at the time, and none of their arguments existed before March 2016.
Meanwhile, there's Joss Whedon, known sex pest and serially abusive person who somehow finds a way to have every powerful woman in his story suffer a rape scene, and openly makes fun of an actress's accent and proficiency with English when he wants to deflect from his tyrannical behavior. But it's okay, because he claims to be a "progressive" "feminist" male. So even if he does all that and isn't even subtle about it, and weirdly implicitly admits that he killed a child when he was young, and says the quiet part out loud re: liberalism's purpose being to pacify the poor so that they don't have to be put down like the mindless hordes of a zombie apocalypse, he's apparently worth defending on a corporate level by WB's executives and fandom at large, and only openly blamed just enough for when WB needs to deflect from something. And it's okay, because he wrote a "good show" once, and you have to "separate the art from the artist". Whedon could straight up be a pedophile and people would be willing to "separate the art from the artist", because something-something Firefly and something-something Buffy.
But you see, Zack Snyder committed the crime of making Superman vulnerable and not an infallible paternalistic force that makes Americans feel comfortable in their exceptionalism. Snyder shines an appropriately villainous light on what's essentially Batman's regular behavior in comics, but instead of the completely goonish idea that Batman has a "no-kill code" (cue a supercut of every time Batman takes actions that are obviously fatal to anyone with a brain, including during the Nolanverse and the current Reeves movie) or the idea that if he kills a single criminal, he's as point-blank irredeemable as the Joker or whoever even though he's A) already acting outside the law, and B) works with cops who uuhhhhhhh have been extrajudicially killing people for the past however many years now, instead Snyder and his team suggest that Batman kills people
and it's wrong of him to carelessly project his paranoia on Superman while turning a blind eye to Luthor being the bigger evil, but he's ultimately able to make amends for his moral transgressions. People didn't like this, therefore Snyder
must be a horrendous person to the core and on every level, and these haters must announce it at every opportunity.
