I read both articles now. I have no reasons not to believe that what you are saying about CZ contacting mining pools to organize a roll back aren't true, but the two articles show no proof of that. They do link to his tweet where he stated that he changed his mind about the roll back, but they show no proof that messages were sent to mining pools with such proposals. Where did you read about the 300 BTC reward he offered for the reorg?

Nevertheless, I am glad his proposal was turned down. I can't imagine what kind of negative consequences it would have had for the network. The miners passed the test with this one. Although, had they done it and succeeded, the faith in the network would have been seriously damaged, and so would their potential future mining rewards.
