The author of the comment in question uses tired populist cliché (elites) and tries to impose their own political views on the reader (you think blackwater is bad).
Which is likely to generate a long, heated and shallow political debate rather than a discussion about the technology (or about the social implications of the technology).
Blackwater being bad is not a political view; it is close to moral truth. I have talked to multiple US soldiers back from Iraq who have described Blackwater committing what would normally be war crimes. However, Blackwater is not subject to laws, so they're not war crimes.
Soldier was in the Air Force, in northern Iraq near the Iranian border. They had a warrant to raid a house looking for a weapons cache. They did the raid with some guys from Blackwater. When they got inside, there was a guy laying on the couch watching TV. Normally, anyone inside a house during a raid would be put in flexcuffs. A guy from Blackwater just shot him, while he was laying on the couch.
