Even without the bureaucracy - it can be other developers themselves who shoot down suggestions for improvement or radical rethinking. About "going blind" - note that the post describes some fish as never developing sight to begin with.

Or they come from another company with similar problems, or have switched from a different language they worked with elsewhere etc.
