Well it looks like POS is closer to a centralized system. although not completely centered. However, POS is more widely referred to as environmentally friendly. and it seems that Ethereum is switching to POS because they want to get support from the Government which is more supportive of the POS system that many say is more environmentally friendly. But I actually see that behind the environmentally friendly there is another agenda, which is easier to control because it is closer to a centralized system.
There is no doubt that POS is centralized. But the fact that ETH has moved to POS for government support, I doubt it, just moved to POS, ETH has been investigated by the SEC, from this action it can be seen that ETH and the government are not related and why does ETH need government support?
It is quite simple, ETH needs the government support for adoption. If the government supports ETH instead of Bitcoin then majority of the government citizen, institution and establishment will tend to use ETH than Bitcoin.
The purpose of moving to POS is because ETH cannot solve problems like gas fees, transaction speed... this makes ETH lag behind its rivals. It can be seen that since ETH gas fees increased, a lot of projects have moved to build on other blockchains and so have users.
They are not on that upgrade yet. The merge as I read is the foundation of all the possible upgrade that is on the roadmap of ETH. Once the sharding is implemented, then that is the time when gas fee won't be an issue anymore since it will solve the scalability problem of ETH
