As others mentioned, they won't be able to continue their business if they keep allowing people to trade without any KYC. If you're mad, you should be mad with the regulations too. If you can't trust centralized exchanges then don't use it, better stay with DEX unless you're a trader.

I'm pretty sure every CEX or even DEX will start to require people do KYC, based on where they're operating. I think they should at least allow people to withdraw their funds if they don't want to do KYC though. So instead of not allowing them to withdraw, it's better to not allow trading and instead allows withdrawal/deposit.
