People should be more educated, but blaming misinformation on uninformed people is like blaming climate change on consumers for driving and not recycling. Why doesn't 'real' news get more views and better advertising money? Wouldn't a trustworthy brand be more valuable for advertizers? Why don't more media orgs have independent funding? Are there any reporter / user owned media?
I wouldn't say misinformation is caused by 'uninformed people,' it's just that people tend to click on garbage. It's a slide into tabloid-ness as media focuses on their marketing ROI.
