It is more like a plea to decentralize the Monero mining network, no one is making anything off of p2pool, unlike all the other centralized pools that charge a fee and reduce the security of the network.
Unless you are solo mining you should be using p2pool and nothing else.
There is a small but growing Monero community on Retroshare, which is fully decentralized and never down.
