To be frank, I don't think the general public cares enough. And the other side is always ready to use children safety, foreign hackers and scam prevention as an argument. Nobody will riot over tech people losing the ability to run their own machines with their own software. It already happened to printers and, most importantly, phones. When 95% of normal activities happen on mobile devices anyway, they will come for computers. They'll run a campaign, they'll lobby politics, cartel chip vendors and start introducing small changes in hardware and OS that will make it always a bit more inconvenient running your own software. Until there's nothing left to defend, and the industry will move on.
