I said no considering small companies that cannot afford many developers working to maintain a totally customized UI library. BUT I think even small companies should create its own UI library by wrapping other UI libraries/frameworks translating whatever the third party library provides to what it's useful to the company. And if in the future they want to change the UI library used, they don't need to change a lot of code, only the wrappers.

I selected no, but…

If such companies also keep the library alive, with patches, new features, and alike, itʼs not that bad. Other libraries way profit from it in terms of new features or gotchas.

Of course, if there was only One Library, that would make a lot of things easier, but letʼs overcome browser differences and bugs before we go to the next level.
