I think there is a lot of Scala usage you perhaps don't see. As an example from the corporate world, at least six major international banks (probably more) are doing a significant amount of their development in Scala, some with teams in the hundreds. That's a solid market for Typesafe right there, which isn't going to go away overnight, and won't be stirred by the existence of the Typelevel fork of Scala. Furthermore, they should benefit from its existence because it represents a means for more people to be able to contribute to and enhance the language, without negatively impacting the stable, reliable releases from Typesafe.
