Wow! I think you're being extremely uncharitable to SPJ, who I believe expressed the sentiment about Haskell originally. There's ton of reasons to not wish for adoption. For instance, supporting commercial use of a programming language is a lot of effort and takes a very different shape to pure language/compiler experimentation and research: more software engineering and less computer science. It is true that the creators probably wish for the product of the research (as in, the successful ideas) to be adopted widely, but that's not the same as wishing for popularity of the framework that proved the ideas. The researchers can focus on their strengths as can commercial compiler/language developers.
