They said "leading innovative framework", and innovative is the key word. The biggest player is almost never innovating, they are usually performing some kind of undeserved market capture.

Indeed, I meant leading in innovation.

React isn't innovating, it's just improving what it already does, but it doesn't do it in a new way.

That makes it stable, and a safe choice for devs. But yeah indeed like the article says, it kind of stagnates innovation in the ecosystem. But yeah I guess that is because React is usually "good enough" in most cases. Not enough reason to use something else.
