There are huge concerns over centralization. As it stands 2-3 entities (e.g. Lido, binance and Coinbase) over 50% of all validators. This is due to a mix of issues (no withdrawal making liquid staking very attractive, 32Eth limit leading to hugely inflates numbers of validators and no stake delegation creating the need for off chain pools). I would say there is about a 1-2% chance that BTC adopts PoS on a good day. Based on what Ethereum has delivered it's very close to 0.
I support bitcoin because it is a pattern that allows value transfer absent intermediaries, binds value directly to energy and computational capacity (work), and has clear mechanisms for any new party to enter into consensus.
In other words, if PoW is attacked by say a governmental entity, a massive mining op or central mining shuts down, it does not fail. The hash rate just gets distributed.
I don’t support bitcoin to get rich. I support it for freedom from tyranny. I support it for independence from oligarchs, banking authoritarians, and a corrupted monetary system.
PoS is a carry over of aristocracy and oligarchs. The oligarchs are just called “stakers” now. And with a name behind the stakers, governments can enter and control the mechanisms. With a massive stake locked in an asset you become vulnerable to control from external forces.
There are so many problems with this pattern one could write, at the very least, a very long article on it. But it would seem reason and freedom is as a fart in the wind these days.
Tldr: Bitcoin will never move to PoS because it is inferior.

This is the main reason why many big brains either moved to Bitcoin Cash or Ethereum in 2017. Bitcoin basically got taken over by Blockstream and other L2 VC-backed companies, holding it hostage with small blocks just so these intermediaries can skim profits off of transactions with their half baked federated solutions.
Rationale is pretty much “if Bitcoin has been taken over by toxic lead developers who are in it for the money, then I might as well look for the next best thing (even if it’s less decentralized) with good developers, and many discovered Ethereum fits the bill.
** big asterisk here as I have spent no time trying to understand how they made it work for ETH and how/if this actually applies to BTC..
