Essentially a lot of the tools we use are only meant to be view layers, and we constantly cobble together supporting layers (models and controllers for example) ad-hoc. Angular handles that off the shelf. I suspect a lot of people are put off by this because it feels imposing and they might not realize they're implementing the same stuff manually, and likely doing it worse.
I used to think it's plain old garbage but realized that's ridiculous. There are reasons people prefer it in some scenarios.
SolidJS is my favourite by a long shot, but I find myself using React because I know so many people I write for and work with are more comfortable with it. I'd be glad to use it more often if it made sense.
