Have you worked with Angular much? I've built extensive component libraries (internal) for my org and maintaining the Angular one has been a nightmare. The frequency of breaking changes and conventions has been awful, particularly in the last few years. React, by contrast, has been a breeze ever since they introduced Context and Hooks.

On the app development side, we dealt with 3 major overhauls of PrimeNG's style system before we decided to invest in a custom library just to eliminate the risk of future upgrades. It took us 6 months to migrate our Angular 9 app to 18 because of the PrimeNG dependency. Granted, it's a massive application and they didn't maintain it properly, but I'd hardly call Angular stable regardless.

And then you have the Vue composition API, which was a major shift from Vue 2.

This isn't to say that React has been perfect. Depending on your stack, there are certainly a fair degree of breaking changes (looking at you, Next.js and react router). But that is far from abnormal in the JS world.
