I think that, as with all social media sites, it's more useful for them to let us speak freely and try to know everyone's true intentions and how we plan for the future, and we've made it tremendously convenient for them to do so by putting everything on a public blockchain so they won't even have to interact with any business before analyzing all of the data.
Also super-powered flags are already a problem in inhibiting free speech and letting people say what they think, governments or not.
