This reminds me of radio advertising on AM/FM - the personalities will frequently discuss how they've used the Service Provider X and you should too! They've received compensation. They're in the business of entertainment, yet are "breaking the fourth wall" to advertise.

I think I need to clarify a bit more though: Sometimes stupid people can be the loudest voice, as in, anti-vaccine folks who cite discredited science and refuse to back down. A more specific instance is when I worked retail - a guy bought his son a Nirvana CD, this one:

He came in with a head of steam at me, mad because he couldn't returned the opened disc, and said, "This is garbage, it sounds like a bunch of home demos!" But that's exactly what the CD was, a collection of demos being offered to people who were interested in such things. He wanted to give it 1 star, essentially, for it being exactly what it was supposed to be. That's...bullshit. But that's an example of how yeah, people might read the review and not find it helpful, but this is how an erroneous opinion is spread. Should moderating that be the role of the platform like Amazon?

For the record, I told him "Yes, that's what that CD is, and while you can't return it, you can probably sell it to a used CD store in your area and get a few bucks back. Here's the CD you want."
