What he wrote is mostly manipulative propaganda and lies. The answer to your question is no. Bitcoin is doing fine and is better off without such immature people like Hearn. He was unable to get his way with XT and so he decides to backstab everyone how lovely.
But at the same time, can you really blame him for leaving a community in general that has been that hostile to him? I mean I can empathize with that, personally.
Good point, he did quit is job at Google to work full time bitcoin development...
That's not a good point. What did you expect is going to happen when you advocate blacklisting? He deserved much worse than what the community threw at him and now he has proven it.
You're passing misinformation, he did not "advocate blacklisting", that was once discussed has a way to prevent the fraud and theft, after discussed it was dismissed because it could not be implemented.
