Instead of going after tech companies I would prefer to see putting more responsibility on the political system. I came to the US in 2000. Back then politics were already bad but now the message is pretty much "The other guys are evil", "anti-american", "racists", "socialist" or whatever. all messaging is designed to put up hard barriers between people that can't be overcome. Social networks certainly amplify things but in the end we need more discipline from political leadership to not constantly incite anger in the population.

With companies censoring more and more information it's pretty much guaranteed that they will also censor information that's inconvenient to them. The internet should be open and stay open.
