There's a huge problem with "endless free coinjoins" - Sybil attackers get endless free coinjoins as well.  As you might imagine, Chain analysis companies attacking the coinjoin pool disproportionately benefit from these free remixes because they have a lower time preference than real Bitcoiners that actually transact.
Chain analysis companies can sybil attack Wasabi mixes as well. All that is necessary is to control x number of inputs but I don't think they need even waste energy doing that since all of the same bad post-mix practices are just as possible when you use Wasabi.

On top of that, there's multiple instances of Wasabi mixes being de-anonymized by normal bitcoiners without access to industry level chain analysis tools. The recent hack on Rick who lost 25 bitcoin for storing his coins in a password manager has had help from the bitcoin community to track down some of his coins to Binance. https://twitter.com/RMessitt/status/1724135148055097364

I'm sure chain analysis can easily follow the rest with all of their tools.

I am not spreading FUD, address clusters from common input ownership and peeling chains from leftover change ARE unique to Whirlpool coinjoins.  

You are spreading FUD about Wasabi's coinjoins because common input ownership is not revealed, and peeling chains are not produced (unless you are a whale with more coins than all the other participants), and there is no coin control necessary.
Address clusters and peeling chains are absolutely possible with Wasabi.
- If you ever try to spend an amount greater than a single UTXO, you need to merge inputs.
- If you spend less than a single UTXO, then change is generated which give birth to the beginning of a peeling chain.
- If you don't use this change UTXO, then you have a UTXO that sits idle forever and Wasabi has a "dust bug" or "tracable leftovers" as you've called it. 
 
Acting like your privacy cannot be compromised when mixing with Wasabi is blatantly false. They aren't magic. They may offer some privacy in certain instances but not as much as you seem to believe. The user of any wallet needs to be aware of basic privacy practices. Address clusters like merging inputs and peeling chains are unavoidable. That's the very nature of UTXOs. 

Whirlpool does not provide this sort of complete privacy for your entire funds like Wasabi does.  You always generate traceable leftovers:
"traceable leftovers" is a misnomer. Any UTXO can be "traced". You're conflating a bad privacy practice with a mixer "flaw". It's not an accurate comparison. There are plenty of users who don't merge their doxxic change. I know multiple people who use whirlpool and never merge doxxic change outputs and thus they never create address clusters or peeling chains. There's multiple ways to spend CoinJoin change without doxxing yourself: https://www.whatisbitcoin.com/privacy/spend-coinjoin-change

No, I'm not being disingenuous, people following the guide will automatically be deanonymized since they are not using Tor.  The worst possible outcome is that people get a false sense of security (and pay sats for it!)
Your concern about Tor is reasonable but OP is broadcasting though their own node which runs behind Tor so it's not an issue. It seems like you're just here to flex on the OP and tout Wasabi as better than Whirlpool.

Are you affiliated with Wasabi?
