I agree that we need better education or something of the like to also work towards hardening people against propaganda, but I don't see these different approaches to the same problem as mutually exclusive. And while I would want more funding / different methods to be explored in education independently of this, and believe it could yield amazing benefits for society as a whole, I recognize that the first option might be more cost effective
In the meantime, it's easy and possible today to require that all political spending MUST come with disclosure of funding. No more secret donations to Super PACs or Heritage or Hillsdale.
It's literally the first amendment.
Platforms like Facebook would be well within their rights to try and prevent politically targeted advertising, even if it would be a fool's errand. Outlawing it would be unconstitutional.
If they try to prevent "spreading of false information" by political advertisers I've no doubt they will simply be harsher on the propagandists who have a political aim at odds with Facebook's interests, one of which is stopping these hit pieces by those angry that Trump won.
Nobody would be talking about this if Cambridge Analytica worked with Hillary. They simply want to stop their opponents from using the useful tool that is targeted advertising.
Outlawing political advertising is not what I propose. I believe propaganda is different in its intent: in my opinion direct disinformation or dishonesty (with intent) would be a sufficiently high barrier, given that it would require a high barrier of proof that the supporters were seeking to manipulate opinion with lies. This would ensure nobody would be prosecuted except in the most egregious of cases. I also believe this could be a valid exception to the first amendment in the same vein as libel or slander: spreading false information, with intent, possibly for personal gain. The parallels certainly exist.
Furthermore, I believe I would be just outraged if Hillary did this, and I think this is a pointless distraction. I didn't vote for her and I know that she also had her own shady internet propagandists working too. I think we should do our best to make sure political discussions happen organically, from real people.
Nothing new here, seriously. Propaganda from both sides before elections has existed for as long as there were political debates and political campaigns. The fact that we have now systems to make Propaganda more targeted may make it more effective than before, but that's all. In the end, believing or not in Propaganda is the individual's responsibility.
