Twitter’s Ban on Russia Today Ads Is Dangerous to Free Expression

It seems to me that inaction against the spread of authoritarianism, which actively threatens to undermine the democratic foundations on which our right to freedom of speech is built upon, poses as a much bigger threat to free speech.

Seems like every content platform starts out as free speech or at least more free reign (Facebook, Twitter, Reddit), and as they become popular the various minority groups they attract can become larger, more insular, and more vocal, which leads to a backlash against the groups. The companies are worried about that backlash extending to them, so they shut the groups down.

I don't think this is dangerous to free speech, though. There are enough alternative platforms for fringe groups to congregate on that they can't effectively be silenced. The danger is the pervasive lack of diversity, but there's no good solution to this. People want to have their opinions validated and be around like-minded people, and we as a society have made this easier and easier to do, from increasing political homogeneity at a geographic level to users on specific content networks.
