I would say what is bad is all GUI or application development over the web. React solves some problems of application development and introduces others. If you are really annoyed by the problems introduced by React and want a new platform that doesn't have those problems, that's fine, go for it. But be clear that the web is a broken environment for application development all the way down and there's no silver bullet. You will find problems in whichever stack you choose. Analyze clearly what trade-offs you are making and don't think that everything was fine until React arrived, React was created to address certain issues.
Those problems may have been partially addressed by new web-standards, but not all have been addressed, and those web-standards have not been battle-tested hard enough to decide if the solutions are good enough.
React isn't particularly fast.
React isn't particularly organized well.
React isn't particularly pleasant or motivating to work in.
Companies that look into some of the great alternatives will run circles around their slower and dumber competitors.
I think there are just not actively marketing as such.
Or 10x more lines of code with JSX, Redux, Services, Axios calls, data models duplicating server Data models, ViewModels because why not.
All that to display a list of vendors.
