The government has always had a say in the UI if it was for the greater benefit of it's citizen:
- Off putting images printed on cigarette packages
- Warning stickers put on microwaves to prevent people from drying their house cats in the microwave
- Forcing speed meters in cars
- Forcing head lights of cars to be turned on after a certain hour of the day
- Lot's of "UX" regulations in casinos and other addictive establishments
- Licenses to sell alcohol which basically influences where people can find and shop alcohol
- Recently the UK has drafted a law which prohibits supermarkets to stock and display addictive unhealthy food close to the checkout tilts (Mars, Snickers, fat crisps, etc.)
Why should it be different on the internet? Social media has a damaging and addictive negative impact on society, so it need's to be regulated to protect citizens from the exploitative patterns which these companies purposefully implement to hook vulnerable people into their system.
I wonder what makes people believe that the internet should be this sort of "law free" place where anyone can implement all the exploitative behaviour which is otherwise forbidden elsewhere?
