So what happens if, say, Firefox refuses to include these CA's by default? If Mozilla has EU-based physical locations, would they be fined? With seizing of servers, real estate, bank accounts, etc. on EU territory if the fines aren't paid? What if Mozilla has no permanent physical presence on EU territory? Could they still be fined? What happens if they ignore the fine? Could Mozilla executives on vacation in Europe, or technical staff presenting at European conferences, be arrested? Would EU-based websites be legally required to block Firefox user agents? Would they be required to implement network-level firewalling of websites for downloading Firefox? Would it become illegal for EU residents to donate to Mozilla, or would the EU banking system be obligated to divert those donations to pay Mozilla's backlog of EU fines? Would individual users on EU territory be subject to fines or arrest for running a browser without the QWAC root CA? What if they changed the browser settings, or recompiled the source code, to remove the QWAC root CA from the trust list? Would it be illegal for Firefox to put QWAC on the trust list, but implement some sort of local "security enhancement proxy" whose sole purpose is to deny access to sites that use the QWAC CA?
