As for now wala pa talagang truly decentralized exchange. Ginagamit lang ng mga exchange ung "DEX" na titolo pang hype and pang gain ng trust, kahit na mas nababagay na pangalan sa kanila e "non-custodial" exchange, dahil di naman sila "decentralized" in the first place.
I agree to the point na ginagamit lang ang "decentralized" para makakuha ng mga users. Naglabas nga din ng article ang IDEX similar sa iyong comment:
The Word “Decentralized” is Just a Platitude
A lot of great commentary has been written about the misuse of the word “decentralized.” The reality is that decentralization exists on a complicated, multi-faceted spectrum. However, many view the concept with absolutism. In turn, a degradation of discourse has arisen, making the word decentralized all but meaningless.
Instead of labeling something “centralized” or “decentralized,” the community should describe projects by their specific product attributes that arise due to some often-imprecise levels of decentralization. In the context of exchanges, decentralization can be used to create a platform that is:
Non-custodial — the exchange does not hold or manage any funds
Censorship resistant — no one person or individual can shut down the exchange or prevent others from using it
Transparent — open source and verifiable code
Auditable — all trades are written into the blockchain and history is retained into perpetuity
