Absolutely. However, this goes well beyond the issue of elections. It's a much larger problem than elections. It's a problem of great magnitude, and we've seen it in other countries, like Burma, where some terrible things have been happening because social media is basically the only way they get their news. There are some biases, as you say.
It's a very large problem. It's one that needs to be taken seriously, but it goes well beyond the electoral mandate.
