The role of the internet has changed. What was originally designed to allow universities to exchange research has been hijacked by an abundance of false and misleading information.
With such a wealth of 'fake news', the unfettered spread of information is no longer good for society. We suffer from a glut of information, but a dearth of verifiable information.
Net neutrality would allow internet providers to silence those that have a history of spreading false information. It would be a way of cleaning up the quality of information by reducing the quantity of unverified information. This would be good for society at large, even if it is not good for the internet.
