This is completely wrong, your coins can't get "taken by someone who gave themselves the right to do so" since Coinjoins are completely non custodial.
You misunderstood. The quoted part doesn't refer to coinjoins and Wasabi. It goes back to
this post where I explained that just because blockchain analysis gives the green light that certain coins meet the requirements to participate in your coinjoins, it doesn't mean that other services (like exchanges) will agree. It's exchanges and centralized services doing the coin confiscation because they don't like the history of your coins or the lack of one.
