They switched to another blockchain… that has the same exact name and is maintained by the same people. So in my opinion, Ethereum broke the “unmutable” promise after the DAO debacle. You could argue that as Ethereum Classic kept the original blockchain, the promise was kept. But even so, it was the spirit of that promise was broken, and ETC is not maintained by Ethereum. I lost trust on Ethereum because of that and never touched it again since 2016.
