@diathesis Thanks for sharing the link - I’ve never heard the term “Strategy Tax” before.
You only have to look at Scala to see how hard it is to make money from a programming language. Typesafe should have been the commercial entity driving Scala, but now it is called Lightbend and tries to make money with Java software like Lagom, just like Pivotal does with the Spring Framework. They still contribute to Scala, but I think Scala is no longer what they hope to earn a relevant part of their money with.
