The new bitcoin magazine article you linked comes from a Wasabi developer not a more neutral party like Shinobi. The WabiSabi implementation is fairly new, correct?

If we are using biased opinions, I would like to hear Kortik's counter to these points as he seems to have a deeper technical understanding than I do. #[6]

If I assume all these points are true, they would carry much more weight if they didn't use chain analysis. Really is a huge blow to their credibility and effectiveness of entering their service in the first place.

If they are going to use chain analysis to tell them what is allowed, doesn't this defeat the purpose? What if I received coins from some nefarious actor before going into their mix unbeknownst to me? Will I be rejected and flagged? Runs contrary to the service as that is what you are trying to avoid when trying to mix.

If you unwittingly and unknowingly received coins from a nefarious actor identified by a coordinator, then nothing happens. That UTXO just sits there in the original address instead of being coinjoined.

This does not affect the user's privacy in any way whatsoever: All the user has to do is switch to a different coordinator who doesn't consider this coin to be a risk to their business or their customers, and coinjoin it with them instead.

But isn't there only one centralized coordinator atm? That is essentially blacklisting coins which is pretty ridiculous for a privacy protocol. Assuming guilt with no evidence, only that a chain analysis company has flagged it (no conflict of interest for the chain analysis company to do so /s) in an industry based on probabilities. But I guess they are free to do that as I am free to avoid them.

This concern about the possibility of being blacklisted wouldn't explain why you wouldn't want to use the coordinator if you were not blacklisted.

It's like saying your favorite restaurant is McDonald's, but you refuse to ever drive there to eat because you are worried the restaurant will be closed when you get there and you have to go to Burger King right next to it instead.

There is not only one centralized coordinator with Wasabi, unlike Whirlpool which Samourai made closed source in order to try to monopolize Bitcoin privacy as a for profit business. Another Wasabi user posted in Telegram yesterday about how he just made their own coordinator using the open source code from zkSNACKS without permission:
