Just over four years ago, Donald Trump’s Federal Communications Commission eliminated net neutrality rules that ensured a free and open internet. Without these critical protections, internet service providers, or ISPs, were no longer required to provide equal access to all lawful content on the internet. That means ISPs were free to speed up customer access to information they like — either because they agreed with the content politically, the opinion advanced their corporate interests, or a business partner was paying them to give its content preferential treatment. At the same time, ISPs were likewise free to deliberately slow down customer access to content they didn’t like, or to block it entirely.
