Pay attention to what Peter says. Even if you run your own full node, you still don't know who you're coinjoining with. As the old saying goes: anonymity likes company.  

May I also say, that no expert, has ever taken the time to examine the shaky grounds of their 5 participant coinjoins either, because fundamental privacy leaks like this or the default clearnet usage just put us off from looking any deeper.

In contrast, the "egregious privacy offender" Wasabi has no known privacy issues.

"50% chance Scamouraï is run by the CIA" - [ITW Peter Todd part 2]

I mean, the Samurai xpub thing is not relevant for users that run their own node. Samurai isn't for newbs or those without their own nodes. 

And to act like coordinators don't attract network effects (ZkSNACKS) and that anybody can go coordinate on their own with sufficient volume to break heuristics is a bit short sighted. We're talking about end users here.

I don't use either wallet, but would say Wasabi is the more egregious privacy offender.
