The real class action case is that the huge stream of money flow is not cashing in Europe at all, not a cent. Who the f owns the infrastructure? If I buy a domain from and in Europe the money got to stay in Europe.
The real class action is the issue of a fascist government declaring antifascism terrorism, making all bank transfers void, seizing their domain (.org). They could do the same to ICC and ICJ, or anyone they dislike really. Most root-servers are located in America, too.
That some company is behind .com or some TLD and earning some money with that is a nothingburger.
Then buy domain operated by european registry?
