except this isn't a game of sports and a private company doesn't gain anything from attempting to "hack back" a foreign adversary. It just costs them resources and makes them an even larger target. And given that those adversaries are in all likelihood state sponsored the actual opponent is the US government, which is abdicating their responsibility.

It's like saying "the police doesn't care any more citizen, so you know just punch back". It's also incredibly dangerous btw to tell private firms they have the authority to engage in what is basically an act of warfare.
