There are many issues with that.
Many voters don't have the time to spend on political education, nor the interest - I actually think the lack of free time is an issue in a democracy, and it's why elderly people are such an active demographic during elections
And the elephant in the room is that propaganda works even on informed people. Just making a name familiar to you is money well spent for marketers, even if you don't buy the claims of the ad it's still an advantage.
Media is designed to be addictive in our days. We should start treating it for what it is - if something disguising as news is actively attempting to evoke an emotional response for the reader/listener to get them hooked, that thing is harmful and not a public service (state funded or not). I don't have a solution, but I do think that at some point in the future we'll look at clickbait and disguised ads the same way we look at tobacco or asbestos now.
