Disregarding the strange rant for a moment, is it purely for tracking purposes or does it just use their CDN for CSS, images etc?

(Wouldn't be surprised at all if it was tracking, this is Facebook after all, but there are plenty of perfectly legitimate reasons to use a a CDN)

There's a bunch of absolute paths in the generated HTML that link to inline icons and other chaff. As I'm never actually logged into FB, they show up as broken images when you view your offline archive.

Do share what exactly it was before accusing people of covering it up.

Have you not heard of AB testing?

It's certainly possible that one of the biggest arms of surveillance culture can AB test people on what they do with their exported FB profile.
