Honestly it's the politicians (specifically conservatives) fault for allowing this completely foreseeable and predictable problem to get to the point it has. This could have been addressed much easier 10 years ago with some legislation requiring social media companies above a certain size to operate on first amendment principles. But instead, we've let the problem fester and the tech companies have grown to a point where they're more powerful than the government in some ways and a lot more difficult to reign in. These companies are essentially spitting in the face of Trump and conservatives in general, then telling the public "nope we treat everyone fairly" while trying to hold back their laughter. It's disgusting, and I have absolutely no confidence that they'll ever be held accountable.
