Repeating "ultrasound money" memes. That specific meme has to do with state level attackers blowing up mining farms. It has nothing to do with changing issuance. And the entire premise is that an external force comes in and tries to co-opt it.

That isn't relevant to the conversation of stakers having misaligned incentives to change the rules. The most a state level actor can do is censor transactions if they were to take over a chain.

With PoS you'd need to slash the validators stake on a fork; which isn't going to happen because the stakers run the validators everyone is using. You already saw this with the steemit takeover.

In PoW coins, the miners and validating economic nodes are two separate groups. Watch what happens when exchanges slip over to Eth2 nodes and call it Eth.

During the BCHA/BCH split the exchanges were the ones that decided the ticker. Most users have ZERO CLUE about what happened. They went on their with their lives calling the fork the exchanges chose BCH. Once exchanges are validators there is no bulwark against changes.
