This author assumes that open sourcing a package only delivers value if is added as a dependency. Publicly sharing code with a permissive license is still useful and a radical idea.

This is a point where the lack of alignment between the free beer crowd and those they depend on is all too clear. The free beer enthusiast cannot imagine benefiting from anything other than a finished work. They are concerned about the efficient use of scarce development bandwidth without consciousness of why it is scarce or that it is not theirs to direct. They view solutions without a hot package cache as a form of waste, oblivious to how such solutions expedite the development of all other tools they depend on, commercial or free.
