It really looks amazing on paper, but in reality, the footer of people’s "description", memo or whatever is really like a big ad and people scroll below it as soon as possible. And if you have ever worked in marketing you would know, that the old ads don’t even work anymore.
They had to upgrade, that is why the ads are on your main feed (on facebook or twitter), because your eyes are not even looking at the ads. Or they do, but your brain is not even catching it anymore.
