Yet why should people rely on Instagram to know to vote?

Nobody said they should. But people are idiots and make conclusions from what they read in there anyway, so they should be liable if they spread misinformation or if they, like Facebook, contributed to a coup in Myanmar or had a role in the attempt of taking the US Capitol.

Instagram is a social media that has nothing to do with real world or politics of a country.

You really need to live inside a jar to believe that nonsense.

Remember Cambridge Analytica? One of the selling arguments to the Trump campaign was that they helped the triumph in my country of a right-wing party by using Facebook. So “nothing to do with real world or politics”? Fuck that noise.
