It definitely had to come from somewhere, external pressure, etc. As long as the devs are known, and their tech (in this case CJ) is used for activity enforcement's come to know of, they're going to have to comply (or face some very unsavoury penalty to be sure).
MetaMask I expected, not Wasabi so soon but yeah, probably naive to think that they could have gone on without getting tapped. Sucks ass, but we're going to have to increase the threshold for our worse expectations.
Things like this should definitely be expected to come at some point if you think realistically. But yea — kinda earlier than expected, but at the same time I think we already saw mixers get pursued by the authorities so I guess I'm not THAT surprised.
Anyway, wish some devs would just fork the privacy coinjoin stuff and integrate it to Bitcoin Core; if it's possible, that is.
