There is no wrong claim.

you retain control over protocol once it switches to PoS

This "was" true since

it was not always clear how PoS would be structured

As I also explained, stake still allows control over block production and it's arguably worse that there is no on-chain voting for upgrades.

Btw ad hominem is not cool. I'm a decentralization maxi and very proud of it. Without decentralization, there is no value in any of this and considering how unsecure some protocols are with tens of billions worth of exploits every year and users losing fees on millions of failed transactions every month, these don't offer any advantage over legacy financial products. The only advantage we have is decentralization and there can be no compromise there.
