The arrest of the Tornado cash dev sure put an example. If node operators are doxed, they sure expose them self to a big risk. Now it is not the 100% same case as Tornado, since there was one man to go after, while here will be a 100, but still something can be done. Furthermore if there is any legal entity that is responsible for development, like foundation or similar, that can be at risk. Like it or not, these are the real threats. Devs and node operators should be all anons and that is hard to do in todays environment even if they wanted to.
