This is gonna be the death of democracy when political advertising comes into play (as it already has).
“Point this piece of fake news at uneducated 40 year old single parents in <area>” - "point this piece of scientific news reinforcing my party’s message at university students who are interested in " and on and on.
My mom gets fake news advertisements on Facebook all the time, occasionally they are political in nature. Platforms aren’t doing their due diligence at all, so government must act to restrict the information that can be collected and the specificity of the targeting that may be employed.

Keeps out the new users we’ll need to keep this place alive, you mean
