I'd agree, but there's little reason to speculate. If you can't run it (disabled by fuses), I'm not sure it matters... if you want to confirm the silicon presence, then a little concentrated sulfuric acid to take the package off, and just a 100x microscope and you'll be able to see the memories for the uP.

A strange accusation without proof.

Fair warning I can't open the Tweet, Twitter is blocking me... or maybe I uBlock them? so I'm making a statement in similar unsupported ignorance.
