I wouldn't count the Snyder films. They have fans but are way too divisive to be considered a clear hit for the character, to the point where the studio is chucking Cavill despite still being interested in the role. The extreme hate and the extreme love the take gets mostly exists in the fandom sphere. Like Myskin said, the overall reception of that Superman among the mainstream is a resounding "meh."
The brainwashing counts (at least halfway) because it was heavily foreshadowed as going to happen in both BvS and the Snyder Cut, plus we have his delirious state post-resurrection where he attacks the League. Combined with the character being so poorly fleshed out in this iteration, the main visual of the movie is angry/stoic Superman with flashing red eyes even when he's not being brainwashed. I'd also say while the DTVs don't count for nothing, they are more of a niche product than the movies or Injustice games and aren't reaching as wide an audience.
Superman being brainwashed into doing evil things is only superficially different from the Injustice stuff. People don't need to be told the specifics of the differences because it sucks either way, and that's why people tend to lump it in together, because the end result is Superman being a frightening figure that needs to be taken down either way. While other heroes get brainwashed, does it happen with the same frequency and high profile stuff as Superman? Because the big shared cinematic universe that WB launched had the idea of brainwashed evil Superman as one of the ultimate threats, and so far he's the only one being shown in the advertising of the SS game. And now we have confirmation that some people in charge want him to be more authoritarian.
Yeah, I don't think the Superman and Lois show should be downplayed and the upcoming cartoon and stuff like JL Action doesn't count for anything, but people are noticing these trends and hate them for a reason.
