Something tells me that Google won’t be turning down fast food companies that want to advertise with them, or reducing recommendations of channels that show off/review fast food a lot.
Maybe I’m being cynical, but this seems more like a “let’s get some good headlines” ploy than something that will seriously help anybody.
I don’t know what the best course is, but screwing over channels that promote exercise and healthy living doesn’t sound like a good option to me. Even if they can exacerbate some people’s perceived body issues.
