Seems it is case of yet another page that relies on (google) analytics to work properly: it works with Enhanced Tracking Protection turned off. (Shield at the start of URL bar.)

So it is basically "you have to let us track you to read our content". /Bold move, let's see if it pays off…/

EDIT: NM, seems it is unrelated to tracking after all; just some spaghetti code that (presumably) attaches load event handler too late.

Can't say if it would have been a waste of time but otherwise I agree: there's enough other stuff to read on the internet.

Goodbye.
