Coinbase is bashed on because their practices include ponzi scheme endorsements along with setting themselves up for regulatory capture forcing their users to KYC themselves.

Seen what's happening in the EU with the new bill in passing? Likely to happen everywhere else, which affects anyone and everyone with KYC stacks, and any establishments that host such wallets. DEXs existed before coinbase, but users chose forgoing responsability and effort (proof of work), instead of taking full custody of their stack.

If your stack is KYC'd and has not been mixed, you will be limited. Linking one's BTC stack to the legacy finance system was never going to work, they were made holisitically incompatible from the ground up.
