We really really really need some legislation about governmental agencies using privately owned companies to announce things. There was already some for radio/early news, but the landscape has changed so much, and it bothers me a ton that these platforms are being used.
The government has always used privately owned companies (newspapers, news channels, news websites) to make announcements. Social media is just the latest iteration of that. The government operating its own websites is in fact the aberration, and I'd wager the vast majority of people don't even know they exist or visit them. So not sure what such a law would accomplish.
