I have little to say about this because it's basically nonsense.
The top 100 accounts already own 35% of the network and rising ... that would give Lido and Coinbase a combined 51% of the stake
These two statements are completely incompatible with each other, for example. Also, the top 100 accounts only holding 35% of the network is remarkably good. And Lido is not controlled by a single individual or organization. And holding 51% of the stake means nothing on Ethereum, it works differently from Bitcoin. And the Gini coefficient is something that applies to national economies, not to blockchains. And I could go on, but this is just nonsense and you clearly have no idea what you're talking about.
It's not really ignorable, though. If it was just Trump the private citizen rambling this nonsense, sure. But it's the President (elect) of the United States.
Elections have consequences and this is one that the US can't wave off. They put their mad king on the world stage, they own the boos he gets.
