It’s not worse or better than a social platform. It’s an entirely seperate tool. Broadcasting your official government messages through a community owned by other people that could delete your comments on a whim is not ideal. The people have already decided to put the owners in power through democratic elections, which are lightyears beyond the whims of narcisistic billionaires, admins and biased social media polls.
Why would a government subject itself to potential censorship of whatever admin is running their instance? It makes perfect sense for a government to host their own instance from where they can freely broadcast announcements.
And the free market has proven to be unreliable. You’re subject to whatever billionaire is ego-tripping at the top of whatever platform you’re using. The will of the people is nowhere to be seen.
Also conservatives: let’s murder the gays!
