Then there are those ads in YouTube videos and blog articles purporting to offer the reader something valuable when, in fact, they're packed with falsehoods ("xyz changed my life, and if you want to check it out, please click on this affiliate link").

There are other ways to reward an author or a website. For instance, I block ads on sites like Haaretz, but I do subscribe to them because I believe quality content deserves compensation.
