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.
