We absolutely expect public utilities be shut down temporarily when danger exists. This happens with gas, fire, electric. In 2001, when USPS first encountered the 'sealed anthrax envelopes' problem, they shut down lots of post offices for quite some time. Your framing suggests that Firefox Send was a 'public utility', held to the same standard as a power company or a gas company, required to provide service to all who seek it. Firefox Send was not a 'public utility', though, and so it need not be temporary to shut it down in the face of attackers. Apparently the Firefox group decided to make it permanent. What if Gmail was shutdown without notice tomorrow? Would any lawsuit have standing if refunds were issued that same day? Would free users have any recourse whatsoever? It isn't a public utility, right?
