I would agree here that the combination of being "closed to collaboration", the slow pace of development lately, and really infrequent communication from the sole owner/leader/BDFL does send a weird vibe and raises some concern regarding what direction the language is going to be going in in the future.

One of the big reasons, in my opinion, for Clojure failing to fulfill its potential as a mainstream language. Clojure had SO much going for it then it just flatlined. Sad indeed and very much down to its stewardship.

Isn’t one of the beauties of lisp is that you don’t need much from the language creator. It should be far more stable than non-lisp languages, and you can implement most ideas with macros outside of the core language.

You can get a pretty long way but there are still things that need to be improved over time. For example Clojure still 7 years after the java 8 release doesn't have great integration with java 8 functional interfaces, which is a pretty big detriment to java interop. I saw this patch which seems to have been submitted by a community member https://clojure.atlassian.net/browse/CLJ-2637 (not sure if the author is a core contributor or what), but even after month no comment from Rich or anyone else on the team to indicate if this is a good idea, if they'd let it in or what.

Maybe not, but I do agree with him, too many people in open source feel entitled to get stuff for free (beer) without contributing, many corporations that leech on open source as well.
