In the social media age we're in now, more and more people are looking for news that fits their own opinion, rather than neutral reporting or anything that challenges their views.

Most users on Twitter, for example, that post about politics - and if you look at the posts about a political topic it bears this out - are on the left or liberal side of politics.

So left-wing political users have greater numbers on Twitter and are more likely to get their way in complaints (through having a louder voice) about other users' behaviour, than the other side.

It's just better business for Twitter to favour the greater number of users.
