This is the same as Microsoft doing a report for the government saying Windows is the best desktop OS.
In regards to the quality of the document; the tables are horrendously formatted and the note numbers are highlighted as if clickable links (blue underlined) like the links at the bottom of the document but are not actually clickable. Overall the wording in the document is basic and lacks any real information.

Yes, I agree it's a basic document and I don't disagree with your points... Why didn't you say that to start with, instead of being personally rude about the author?
You had to research the author on linkedin, rather than simply looking at the bottom of the PDF where he clearly identifies himself as a Sales Engineer?
Yes, how about titling the HN thread "Canoncial creates report for UK Government ranking Ubuntu as most secure"
Then noone would have upvoted it and you'd have had less opportunity to be condescending.
