>>The people with a lot of stake in the system can change or prevent change to the system. This is very misinformed. There is no governance by stake vote in Ethereum. The protocol is immutable absent a user willingly updating their node software to run a different protocol. Stake is used exactly the same way hash generation hardware is used in PoW: to determine what share of blocks a person produces. This is safe in both Ethereum PoS and PoW as long as the assumption that 51% of block generation capital (stake, and hashing hardware, respectively) is controlled by honest parties holds true.
