I think you missed the part where Lily basically orchestrated and coordinate with a large group of Vtubers for a few weeks before the drama happened to coordinate the doc drops, the posts and everything else for maximum vilification and harassment and all that over a personal grudge and a bruised ego?
And that's not even a lie lol. Lily herself admitted that so it comes straight from her mouth!
Sinder is absolutely not innocent, but her "crimes" are grossly overinflated and heavily curated and what was done to her doesn't really paint Lily & Friends as exactly the innocent angels everyone pretends they are.
