As reported in this morning’s Daily News Roundup, Glenn Greenwald’s latest piece for The Intercept takes a look at how western intelligence agencies “are attempting to control, infiltrate, manipulate, and warp online discourse, and in doing so, are compromising the integrity of the internet itself.” The report covers two tactics of UK spy agency GCHQ’s secret unit: “(1) to inject all sorts of false material onto the internet in order to destroy the reputation of its targets; and (2) to use social sciences and other techniques to manipulate online discourse and activism to generate outcomes it considers desirable.”

The following is a sample of the wide spectrum of reactions to the Greenwald piece from journalists and other commentators on Twitter.

Greenwald writes "these documents leave no doubt" GCHQ is infiltrating online communities, but the PowerPoint slides show no evidence of it. — Charles Johnson (@Green_Footballs) February 25, 2014

.@ggreenwald's latest is, hands down, one of the most important revelations to emerge from the Snowden leaks: https://t.co/QaxWxakpHk — Sebastian Jones (@sebastianojones) February 25, 2014

Seriously, report on at least one "false flag" operation, at least one "honey trap" – slides are not very informative. #Snowden #journalism — Tom Watson (@tomwatson) February 25, 2014

Breaking: Spies are taught to use deception, psychology, and trickery. Also breaking: Water is wet. — Dan Murphy (@bungdan) February 25, 2014

This @ggreenwald story is amazing in that it shows the govt teaching how to do textbook online stalking/harassment. https://t.co/qIw9vnakwO — Garance Franke-Ruta (@thegarance) February 25, 2014
