it seems like you are making an even wilder assumption thinking that everyone using Wasabi is a newbie jerk who doesn't care if their not-so-private coins become 100% KYCed.
Doesn't seem that wild to me. If you still believe Wasabi is a good option after the numerous lies, the incidents where their software was caught to be flawed, the blacklisting update and their cooperation with mass surveillance firm, then you're naive to think it's superior solution. If you are tricked into believing that funding blockchain analysis for the sake of your coinjoins is a clever choice, then you surely can be tricked into believing some sort of other nonsense for the sybil attack as well.
I personally hated the fact that they took this path, but the chainanalysis/censorship isn't a concern to many people
If chain analysis in a privacy-protecting software doesn't ring a bell to you, then I'm pretty confident that a silent sybil attack will neither.
