The scale argument is really just a chicken-and-egg thing. A few years ago, people were saying the same thing about how Vue wasn't "proven" at scale. But these days there are sizable teams using Vue just fine. The entire point of the components-first paradigm is that you can scale a UI fractally.

Large teams were using jQuery back in the day, with none of that HMR prettier-on-save Redux devtools fanciness. There's nothing inherently "unscalable" about the technology, especially now that most frameworks more or less use the same framework design paradigms.

This is just a cost of switching consideration. For better or for worse, first movers advantage is a thing. You're also not likely to switch from date-fns to dayjs or postgresql to mysql because you are invested into your choice of technologies, even though each pair might in theory be perfectly interchangeable.
