Don't use Wasabi in the same sentence as "mixer." Some people can get offended by it and start screaming.
But Wasabi fall under the category of decentralized mixers so they are still mixers. Or am I wrong?
Definition of mixer getting blurry these days. In past, i'm sure it refers to centralized service where you need to trust them. But these days, some people also include all form of CoinJoin as mixer.
I think I saw on a thread that Kruw posted about this that people can still use Wasabi conjoin. His posts was after the news that Wasabi no longer providing conjoin service. I hope he will get notified for me mentioning his username so that he can post here also.
You can still participate in coinjoins with the Wasabi wallet. It hasn't stopped. Wasabi's default coordinator, zkSNACKs, has stopped its operation. You can't connect to zkSNACKs any longer to participate in coinjoins, but you can do so using any other coordinator if you want, including the one operated by that person you mentioned. The worst human being on Bitcointalk.
FYI, there some website or webpage which list WabiSabi coordinator such as
https://wabisator.com/. In fact, there are other CoinJoin wallet out there such as GingerWallet (fork of Wasabi Wallet).
