>You seem to be confusing ITAR compliance with some sort of security classification
This is exactly it, that may be the source of their posts? Being covered by ITAR has nothing to do with whether an American could just go mail order it online let alone chat about it. As a regular American civilian with zero government clearance of any kind, I own a bunch of ITAR controlled stuff. As a category it covers a pretty wide array of technology even when it doesn't seem to be in any way particularly sensitive. All of my suppressors for example are subject to export control, or NVG or FLIRs even when it's ancient tech everyone in the world has. Apparently so can things like optics. It wasn't that long ago that the US government tried to insist that mere encryption was a munition subject to controls!
