PoS will be controlled by US-based custodians, which certainly have a tremendous incentive to siphon as much value from the currency as possible.
PoW has a much more diversified set of actors with competing interests, which makes it much more difficult to change the rules. This is a feature not a bug.
No it's very different. Bitcoin consensus is achieved through a combination of mining actors and economic actors. PoS collapses this into a single group: custodians.
Yeah, I'm a big ETH holder, but this is honestly what worries me about the POS merge. I think the fact that Bitcoin miners have to sell to fund their operations is a nice feature and keeps them in a separate class from the custodians. Economic incentives that merge validators with custodians could create a feedback loop that concentrates too much power in the wrong places. That being said, ETH has a thriving DeFi ecosystem and a ton of smart people working on it, so I'm not betting against it.
