Binance have launched a DEX that doesn't require KYC as far as I know and its quite user friendly just it hasn't received the same volumes as the CEX version of the exchange, but these services may become more popular as more regulation is put into place that requires FATF guidelines to be followed and they can still operate without these restrictions
The principle of decentralization is not always applied in their DEX, they have previously held an initial dex offer (IDO) which requires Kyc to participants. They also monopolized coins in binancechain / bep-2 (cannot be used in other dex), and remain evidence that they are still obedient to centralization. To my knowledge only McAfeeDex thinks about active decentralization, but their achievements have not yet been seen.
