But the same hypothesis, I want people to "clean" their UTXOs from "taint"
If by "taint", you mean the list of coins which are treated unequally by chain analysis firms (some of which do get funded by the US government), then we actually don't know what will happen, and probably neither any Wasabi developer knows. As I said, their coordinator makes a request with Coinfirm and will enforce that UTXO list to the coinjoin round. Your coins could be accepted even if you're wanted by the FBI, or could be refused even if you're innocent.
You don't know? But a centralized entity making claims such as zkSNACKS should be regulated by an authority in case those claims aren't real, no?
I still don't get where you're confused. Which claim by zkSNACKs is false if they approve a coin which is deemed as "naughty" by some chain analysis firm?
Given that 9 out of the 10 inputs were accepted, you can conclude the round is not under attack since 9 out of 10 would have to be rejected for the attack to be effective.
If random inputs are getting rejected, shouldn't that be a concern since the chain analysis company may be trying to weaken the coinjoin?
