Any form of Proof of Stake isn't really decentralized, often as a result of a single or small group of users who have minted the entire supply. Other users are then expected to purchase the supply rather than generate it themselves. The sale price on exchanges is often spoofed due to the nature of the low liquidity and ease of wash trading.

I am not saying dPOS is bad and even think it might be a good tradeoff for building real world applications with moderate decentralization, but claiming you can achieve "full decentralization" with dPOS is kinda ridiculous.
