It was pushed upon me by management. I would have opted for Svelte or Lit. So I hate it, I hate writing code in it, I hate that it wants to control all your DOM, I hate how they "re-invented" HTML with JSX components and how the code now looks like PHP, as JS wasn't annoying enough by itself. I hate how it makes accompishing even simple things a PITA. At least I can use Vite and not bother with their opinionated tooling. There you have it, these are some reasons for all the hate if you had to ask.
