It would be far better to state the metric they're using, i.e. "GitHub Stars !== Usage: React downloads still surpass Vue and Angular"
It's taken React about 2-3 years to go from being head to head with Angular(JS) to being the dominant frontend ecosystem. I expect within 2-3 years Vue and React will be on far more equal footing in terms of usage and jobs. (Assuming something else doesn't come along and topple the current trend towards reactive frontend tools.)
