Sure it has a lot of staying power because of network effects (and qualities like backwards compatibility and gaming). But it's not a terminal, self-reinforcing snowball, force of nature like the article implies React is.
There's some properties that ensure it's moat. Developers need to learn React and there's not much transferability of knowledge from the underlying tech. If I know Debian, I can understand most of Ubuntu. However if I know HTML, I'll probably understand react even less. This is a great tactic of having a vendor lock in not only at the infrastructure level of a company, but at the programmer level.
This too shall pass.
