Why would this be flagged? It is a good report with lot of information and analysis to gratify intellectual curiosity.

[flagged] on a post means > N users flagged it for a fairly large value of N. We don't know why users flagged it, but in this case I'd guess it's either because the material is politicized or because it requires a registration to download.

HN hasn't proven capable of discussing articles like this without devolving into a partisan spat, so I'd say the flags are reasonable.
