I'll recognize that Samourai and Wassabi aren't the same and have many differences, but also people considered them competitors.
Having your competing product's founders arrested and their services shutdown sounds pretty alarming.
It would be pretty awkward if Wasabi faced the same end, it would only mean that all the bending over to the government never paid off.
Who would you blame in that case? Given how ferocious feds have been I wouldn't blame the developers.
As stated above, Tornado.cash developers also did their best to cover their ass and avoid having their lives ruined by federal indictments, and yet for the feds it wasn't enough. And as we saw with Samourai devs, one of them was even arrested in Portugal. Even if he doesn't get extradited, he's going to face charged difficult to combat for sure. Prison is never an unlikely scenario when the U.S. goes against you and you're in a western country.
