Again, you don't answer the question of what's the difference between a image pixel or javascript logging that you visited the site vs nginx/apache logging you visited the site?
You're upset that OP used an image or javascript instead of grepping `access.log` makes absolute no sense. The same data is shown there.
It's rude to tell people how they feel and it's rude to assert a post makes "absolutely no sense" while at the same time demanding a response.
One difference is intent. When you build an analytics system you have an obligation to let people opt out. Access logs serve many legitimate purposes, and yes, they can also be used to track people, but that is not why access logs exist. This difference is also reflected in law. Using access logs for security purposes is always allowed but using that same data for marketing purposes may require an opt-in or disclosure.
