Yes, but consequences of the #FTX fiasco are even broader: people stop trusting #EA, and politicians seize the opportunity to meddle with blockchains for their own gain.
I think "people stop trusting crypto" is a bad thing. But that's debatable.
You are right in that ripples of bad actions are also consequences and thus should be considered by consequentialists. But then, someone secretly committing a crime or deception for the greater good, and never being caught, is a good thing? That's the riddle for hard-core consequentialists.
