@darkdimius[0], the person who tweeted the referenced tweet in the article, was arguably the primary contributor to Dotty[1] behind Martin Odersky (Dotty will be Scala 3, the next major version of the language).
Once he finished his doctorate at the EPFL, off to Stripe he went, bye bye Scala. Tough industry, on the one hand Scala benefits from a revolving door of high level EPFL doctoral students, and on the other the talent pool shifts around as students come and go.
Money talks, companies like Stripe have a leg up in that they can fund full-time engineers to work on projects, whereas institution backed projects typically have a much smaller pool of long-term engineers to rely on (JetBrains, for example, has something like 40 full-time engineers working on Kotlin/KotlinJS/Kotlin Native).
