Yet, your ISPs don't give you access to the full Internet. First it's porn (age verification), then it's soccer, then it's social media (ID verification), then it's libraries. Soon, you even stuff that you take for granted, such as playing an online game, may require age/ID verification. At this rate, all you will be able to access soon will be center-left Euro propaganda.
Many parts of the US require age verification for porn as well.
The ISPs do what our elected governments direct them to do. It’s how democracy works. If you don’t like what people are voting for, get into politics and talk to your community. Or at least email your MEP. There is no conspiracy here.
Are you forgetting how the Americans blocked Stormfront and Silk Road? They don't have full access to the Internet either, they're just not so obviously totalitarian about it as the Europeans.
