We pay for internet access. When I first used the web in 1993, the internet fee was covered by the tuition I paid, as only universities, government and a relatively small number of corporations were connected. Later, ISPs were formed and we began paying for home access. The "entitlement" we pay for, IMO, is access to a network free from surveillance and advertising, or at least one where we can navigate around that. The 1993 web was full of free content. Few web users paid for anything. (As remains true today.) The beauty of the web is that anyone can set up a website. However no one is entitled to traffic. There used to be this idea of "netiquette". I think it is fair to say that these enormous websites like Facebook with massive traffic are playing by their own rules. They do come across as having a sense of entitlement. It is not their network. It is
our network. Most if not all of the "content" they use to draw the traffic they get is user-generated. You pay your fee and you are entitled to access the network but (arguably) that does not include conducting mass surveillance and sustaining a massive advertising campaign that targets people personally.
Tha value of Facebook is in its users, not the people who write the website's PHP and run the servers. It is commonly agreed that writing a Facebook clone is not a difficult task. That value is the users. There is a reason Facebook will never charge a usage fee to anyone.
