This is actually a much wider problem on two dimensions:
1. Beyond personal finance, a LOT of content out there right now is basically content marketing for something that's crafted more around "can it get SEO traffic" and "can it convert that traffic to something monetizable". It's just a giant funnel.
2. Even in personal finance, it's not just content. A lot of products that in theory should be helping you improve your finances are lead generation funnels too (especially the free ones). In other words, the marketing funnel extends beyond just content and pervades the very products we use.
For instance, a really popular (tens of millions of users) personal finance product just sent me an email recommending that I invest in art since "art has outperformed the S&P 500". It was an ad, but you'd have to read the fine print to see that. Another popular one (over 100M) has a tab on their site called "My Recommendations", with fine print saying "We suggest offers based on your credit, Approval Odds, and money we make from our partners". It's all for credit cards and personal loans.
