The use of smartphones has demonstrated, I believe, that people will blindly chase their dopamine hits coming from a variety of formats because it is ingrained in human nature. The dopamine reward pathway gives a good feeling and people are naturally inclined to follow the path of least resistance to more hits. If an organization or app tries to fight this, then people will simply use it less.The way this has been resolved in the past, is that the "trash" news is relegated to the riffraff, and more reliable sources of news are used by the wealthy. The problem, is that even the mainstream news was of the trashy click-bait variety, even in the past going back many decades, if not hundreds of years. Even the news sources that are supposed to be higher end will succumb to the greater speed and greatly accelerated news cycle.
How can industries fight against this human nature?
Industries need to have faith in basic human nature. They need to let everything go viral and stop picking winners and losers. Sunlight is the best disinfectant, after all. We need to have faith that the truth will eventually win out. In 2019, when there has been suppression of speech, that has merely given ammunition to the toxic voices. This also takes the form of bad actors pretending to be on the side of the angels, acting in bad faith by using emotional tactics which act to hide the truth.
Contrarian voices need to be protected. This is precisely what Freedom of Speech is for. Lots of those are going to be toxic, but some of them are going to turn out to be valuable. In the past, Freedom of Speech meant that bad messages could be discredited on their merits. The problem in 2019, is that people are trying to do end-runs around Freedom of Speech not through argument, but through reputation smearing and de-platforming. Basically, short circuiting Freedom of Speech by hacking the right to hear. Do this for a good message, and it only de-legitimizes the good message and gives ammunition to the bad ones.
