The point is not to access third party tracking hosts (including web fonts and JS library servers) at all. The number of sites that implement first party server-side tracking to exchange data with other systems (like Imgur) is much lower than the number of sites that “simply added” fonts, libraries or counters from popular delivery networks. Unless, of course, we talk about any site that uses Cloudflare, which is a first party tracking service built into into the web server itself.
