"Didn't want to play ball" has negative connotations that I certainly didn't mean to imply with what I said. It was just the priorities and goals that were different (e.g. back when JJB was still working on Firebug as part of his job at IBM Research, his work on Firebug needed to have a "research" component, as I understand, which led to some differences in approach from a pure "create a product" tack).
