Use whatever works best for you, be it a CSS stylesheet, CSS modules, styled components, CSS-in-JS, whatever. But doing bashing on other people's work just because of the technology used is just rude.
Basically, it's like this:
Lea dislikes an older technology X. She thinks: “If only we could change the past and start from Y instead!”. Lea uses a time machine to introduce Y first. Fast forward to present day. To her surprise, everybody uses X now. “It’s new and doesn’t have the problems of Y!”
