> Miner's de facto control of the network is a huge problem. It's why Bitcoin will never solve its energy use issue, and why Ethereum set up a "delayed difficulty bomb" to force miners to accept changes to the network.

Not sure we should go as far as stating their control to be "de facto" as there has been no major cases of miners splitting a mainstream chain and "winning". Most examples are miners going one way, then slowly dying until they move back to the main chain.
