It is funny to think a capitalist government could regulate anything. If it makes money then it is good. If it doesn't make money then it is bad. If it challenges the current way we make money it is bad, unless it makes more money then the old way then it is good. The problem with social media is it sells its user base to the highest bidder. No sort of regulation is going to stop that. Social media not going to give the government a key to there land. They have lobbyist, secret ninja assassins, black mail, and a endless supply of money to throw at this problem to keep them going strong. What happen when the government try to regulate sugar? Soda companies paid for studies to prove sugar is good for you and is part of a balance diet. What will these social media companies do? For starters they will lie like they currently are stating the technology cannot keep up with fake news. They know when a user gets home they should entice him/her to look at there phone as soon as they walk through there door because they will score a minimal 15 min of eye ball time even if a baby is screaming bloodie murder for them. Machine learning can automate propaganda for entire country, but you telling me it cannot figure out a 1$ bought domain linking to a story for the first time might be fake news? The government will "regulate" social media so they look like they are doing something. The companies will make backdoor deals to benefit them. The american people will cheer with joy knowing there is no more fake news on there social media sites. And when some russian hackers get bored they will buy 10$ worth of ad space on facebook targeting extremist in america. Just so they can gamble what is the best way to get a moron to wave a assault rifle in front of the white house.
