These guys are clueless
1) Any remotely activated kill switch can be activated maliciously by hackers, social engineers, or disgruntled employees, screwing people over. And it will inevitably happen. Hopefully, people will kill every single smart phone owned by everyone who voted for this bill in the first week so that they get how stupid they are. But they'll just blame everyone else for their own stupidity.
2) Unless the phone is irreversibly bricked, you can just reset it to factory settings or wipe the phone and reinstall the OS and you're good to go. So it is utterly pointless, or it leads to massive shenanigans.
