It's becoming a marketing trick for centralized swap services to call themselves non-custodial. I don't know if you have noticed this. I have seen it a few times already. It's clear to anyone that they are custodial but they will claim they aren't, saying that intermediaries and third parties perform the exchanges and not them. Like that magically makes them non-custodial, by shifting the focus on the services they partnered with. The end user doesn't care who does the swap. All they need to know is that they deposited their coins into an address they don't own the private keys for. Who does isn't important.

Wanna bet that there will be no repercussions for FixedFloat and the same negative media attention that eXch got a few months ago after stolen money was allegedly swapped through their exchange? FixedFloat is a fully regulated and trusted exchange after all. A service with the utmost respect for KYC and AML procedures that, as we know, work wonders and aren't subjective and arbitrary by any means.
