There is no reason not to keep going with solidcoin as an open source project. The bugs have been fixed. Quit taking your hate about a developer too far. Hes arrogant and an asshole, but the software is now fine to use and many people wish to continue it. He is not the head of the project anymore with this open source release. Mining pools should open back up and other exchanges that closed should open up again.
CoinHunter made a public claim that he's come up with a "defense" to keep "his" block chain from being affected by a majority of users being on the open source client. He also bragged about his plans to deliberately alter his client to "break" the open source one.
I suspect it's going to take a while for the dust to settle and I doubt Ruxum or bitparking is going to go with an open-source fork until such time as any attempt CoinHunter has made to break the fork has been proven to be a failure.
