Maybe they started to kiss their asses to late

I think it's much easier to ban anything built for ethereum because it's already much more centralized infrastructure.
I disagree. How is CoinJoin in its current form, as used by Wasabi and Samourai, less centralized? There is
one server that can be shut down.
Even worse, if adding blockchain analysis is not enough to keep an operator from going to jail, maybe next step to remain in business is to let authorities backdoor the server and link inputs / outputs? Who knows?
