It's literally just bandwagoning, or people trying to use the tools for things they aren't made for. Like trying to use "Fix Model" on a booth when it's meant almost exclusively for MMD's/XNALara models and specific kinds of gamerips.
Cats is a massive toolbox and there are many very useful shortcuts for basic shit that Blender lacks out of the box. Such as merging bones to their parents, or merging one bone to another, or quickly entering/exiting pose mode, or applying a pose as rest pose, or applying a shapekey as new basis. Those are all Cats features and even the "haters" use those features a lot, often without knowing they're from Cats.
I've used the tool for years, and even made some of my own contributions (hello MMD twist bones!). It's fine.
