It's not our right to blame him because other people are following his ideas. Well he might be right about the power consumption issue but it would not mean that people should freak out. I have some doubts that Elon Musk is behind DogeCoin and some other cryptocurrencies because he Shibetoshi is always responding to his tweets, it's awkward but i won't say that he is manipulating the market. We want to get more sheap btc and we would do the same if we had the influential power that he got.
That is a bit short-sighted. I think if a guy abuses his power and he exactly knows that he has the power to do that, you can't only blame the people following him. If you have power you are supposed to use it responsibly. Maybe he even does and we just don't know it yet. He pushed DOGE into the limelight and there may be good reasons for him that he just yet hasn't shared.
