This created in the audience certain expectations about what it means to be famous. Don't treat the audience wrong or do anything too far outside those expectations or face the audience's wrath.
The internet changed what it means to be "famous" because the internet is media access. Unfortunately, the sociology of the audience hasn't caught up and often still apply the old expectations.
In the past, it was possible to walk away from fame because it wasn't your normal life. Being famous was a job you could (usually) leave. However, a lot of people that have become famous through the internet cannot leave. It was their normal life that became famous. Tight coupling between fame and personal life causes or amplifies a lot of these problems.
For a much better explanation, I highly recommend watching Innuendo Studios' video essay "This is Phil Fish". In spite of the name, it isn't really about Phil Fish. It's about everybody who isn't Phil Fish and how they (miss-)handle internet celebrity.
