What does referencing mean exactly?
Sometimes HTML email comes with the logos and objects needed to render it, sometimes not. When the objects are included it’s possible to render the message while offline. In the case at hand, the logo was not included and the HTML body defined a logo with that unique URL inside img
tags.
In the very least, if we assume the tracking is appropriate and that it’s consistent with the privacy policy and ToS I agreed to, I would still find it objectionable that a government would conceal the fact that they are using a tracker pixel/image by withholding the content-length header. The gov should be transparent about what they are doing. They should even disclose in each such message “we have a tracker pixel in here”, for transparency which should not be an issue if it’s legit. I personally need the content-length header because I’m on a shit internet connection and have a need to know how big something is before I fetch it. So I’m disturbed that all Cloudflare sites (which is like ½ the web now) withhold the content-length
header. The agency at hand is sloppy with privacy and probably sloppy with everything. It’s not necessarily malicious but nonetheless I’m not going to lower the standard by which they should be held to.
I think the author said he was in Australia.. but he felt like it’s an encroachment by the US in some way.
