I'm not surprised by RealSolid's attitude.
It reflects perfectly the FUD articles on solidcoin.info about the "top-5 reasons" and "Ready for Bitcoin collapse" on why solidcoin was so much better than bitcoin/ixcoin/i0coin.
Releasing untested 'improvements' (taken from commits from other bitcoin developers I might add) does not make for a more secure network. The recent attack proves this clearly.
