All the more reason for regulation. If people catch on to the fact that they are being manipulated and abused by the platforms to "drive engagement" they might abandon them or spend less time on them. If the government regulates these platforms so that they are safer or at least less harmful people will feel better about using them giving the government a larger platform to use to control the masses.

I am not trying to be funny or anything but this sounds like "if only fat kid realized that eating 10 apple pies before bedtime might be the reason s/he is fat" We already know what social media platforms are doing, not to just young people but to all people.
> If the government regulates these platforms
This is like saying "congressman care about our debt so they will vote to reduce their own salaries by 90%" - the government is not going to regulate tools they are using to control the narrative/masses etc...
