Keep in mind, ITAR and AECA regulations are concerned with export weapons and weapons systems to non-US entities. The munitions list (USML) includes everything from guns to airplanes. The regulations themselves go well beyond physical assets and include related software, documentation and design drawings. It is likely DEFCAD, if they survive any fines, could reopen if they can somehow verify the downloader does not require an export license.
This is the same set of regulations Robert Gates famously complained[1] restricted the export of F16 spare parts from the US. This platforms has been widely exported and this regulation applies to non-weapons related components i.e., canopy latches, flaps, etc.
