Why is having community mirrors better than one managed by the PSF?

Even with community mirrors the contents of PyPI are still controlled by the PSF, because they control the master server, there is not much decentralization in that respect. 

AFAIK the goal of this exercise is to improve the uptime of the PyPI download service as used by existing installation, MAL's proposal seems like an easy way to accomplish that with minimal effort.
