Why? I assume you are making a joke that Akka is overly complex or?

Akka is clearly a very successful project, being used widely for very high volume systems. Apache Spark removed Akka because so many users were having version compatibility issues between the version of Akka they were using and Spark was using. Enough people want to use both in the same application that the Spark guys rebuilt Spark without Akka.

I might agree with you regarding Akka Streams ;-)

Out of curiosity - which large projects are actually using Akka?
