You and I may understand the need to engage in self-control and personal responsibility for sites like YouTube, but that's because you and I have an insiders' perspective on the dangers of not doing so.
YouTube has precipitously catered to the lowest common denominator and took advantage of their mass gullability. It is overwhelmingly obvious that YouTube designed their site in a way that would get people addicted to the point of needing a tool like this. The fact that they auto-play videos when they know the viewer is a child is downright disgusting.
YouTube did this instead of taking a more sophisticated approach of catering to directors, actors, and producers. YouTube had the chance to elevate the conversation and make digital media higher-minded, but instead decided to cater to people making content for the lowest common denominator - stupid, shlocky trash. The fact that you refer to what YouTube provides as "content" shows that you are not at all concerned with the way that YouTube has cheapened our digital media in order to get people hopelessly hooked.
Just because one can do something effective to increase the immediate bottom line and revenues of their product, doesn't mean they should. I am all about personal responsibility and I do agree that the blame largely lands on the individual at the end of the day. But YouTube is obviously preying on these individuals' largesse and that is just as immoral as being a lazy slob that watches YouTube all day is. YouTube could have taken a proactive approach and showed the world how the web could enable much higher quality video, while limiting your digital footprint. But instead, they did the opposite, which is why I refuse to publish on their "platform."
