"FTX" wasn't registered with the CFTC, only one of the 130 FTX-related entities was registered, specifically "FTX Derivatives US LLC".
So while it takes some time for these things to unravel – it could be the next domino to fall! – there is at least a plausible story that the actual CFTC-licensed entity here (fka LedgerX) was spared the theft & bankruptcy.
That would be a credit to the CFTC's regime, rather than the knock portrayed here.
(I believe that this spin comes from a advocacy group for maximal regulations, firing a salvo to support its factions in DC, taking advantage of confusion about which related but legally-distinct entities are licensed.)
