This article misses that there are pragmatists are not the kind of technology-disinterested "normal" people.
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".
I read both your examples as instances of "following the herd". The expression has negative connotations in litterature and net circles, but that's exactly a pragmatic behavior most of the time.
I'm also "following the herd" when choosing a platform that will make it easier/cheaper to hire (there is an existing "herd" of developpers), or has wide support by multiple vendors etc .
