It seems as though the AMP version of the page relies on these two requests to succeed (Quantcast Choice cookie consent), which are being blocked:

https://cmp.quantcast.com/tcfv2/42/cmp2ui-es.js
https://cmp.quantcast.com/GVL-v2/vendor-list-trimmed-v1.json

It may be possible to shim this, but I don't know if it would be trivial, or if we would actually want to (since it's a cookie consent script that just happens to be classified as a tracker as well).
