Facebook, Twitter, Alphabet and dozens of other major technology companies protested online on Wednesday against proposed changes to United States net neutrality rules that prohibit broadband providers from giving or selling access to certain internet services over others.

In support of the "Internet-Wide Day of Action to Save Net Neutrality," more than 80 000 websites - from big social media platforms like Facebook to streaming services like Netflix and matchmaking website OkCupid - are displaying banners, alerts, ads and short videos to urge the public to oppose the overturn of the landmark 2015 net neutrality rules.
