An individual may have the same values as an early adopter, while having to make the decision to used tried and true systems for various reasons out of their control - one of which might be that you depend heavily on the continued development & support of surrounding ecosystems. Or that large code-bases can't simply switch to a new technology without it being a massive multi-year undertaking which is difficult to justify.
So while the article makes some reasonable points, I think it doesn't fully take into account that pragmatists often use what they use for better reasons than "following the herd".
