As with physical venues that employ analytics, you can easily just not visit those sites that want to know a bit more about how people consume content than seeing "GET /page.html" in HTTP logs.
I'm writing this text to you as a huge free-software proponent so I'm not a "corporate shill" when I say analytics are really useful even to the most privacy-respecting pieces of software, it allows to spend resources much more effectively than making blind decisions about what users want - the vocal users opening GH issues about things are the 0.01% and those people shouldn't be the ones people building webpages, -services make decisions upon.
It is not accurate to say that it is like that the average person who goes to a web site is even in the slightest aware of all the different ways in which they are being used.
