There's simply no reason why Facebook, Twitter, or any other social media company needs to be involved in the business of political campaigns. They're completely free to decline such business and refuse to run political advertisements. It's not like they'd lose much: the income they earn from political ads is a drop in the bucket, proportionally speaking. Given the intense amount of scrutiny they're under, and their apparent inability to make clear, consistent, and sensible rules regarding their content, perhaps it would be better for them to just get out of the business altogether.
