Governments by law generally have the power to interrupt traditional media to put out emergency broadcasts. They could just as easily mandate that for any social media company/channel over a certain size to do business in the country, it must carry any emergency information the government puts out for free. It's important the information goes where the population is paying attention. If that requires laws to make happen, governments are pretty good at passing laws, though they're usually far too slow to make the right laws.
