This reads like an attempt to justify not contributing himself. I read the same thing from sales guys all the time trying to draw analogies between sales guys and engineers. If only projects could run on blog posts and lightning talks...
A great example is melpa and marmalade for emacs. The difference between having a package manager and not having a package manager has transformed the open source project but all they are doing is mirroring a bunch of elisp.
Sometimes just providing the infrastructure to make a project available is the only reason why the project is popular. npm anyone?
