Fair enough, ok. There are counter arguments to that, in that a commercial enterprise running the system has motivators to keep running it that are disconnected from the project - so might be more stable through tough times.. Plus, they won't pull out from the project and refuse to allow others access if they get annoyed with people personally ;)

Ultimately, a community hosted server will tend to be rented from a private company or alternatively will be controlled by members of the community. I guess the only way to improve on this from a decentralised perspective would be to host the project management itself on the blockchain ;)
