> Why?

Presumably to secure the company selling the device’s revenue stream.

There’s a big difference between “any 10yo with $5 for an SD card can download a one-click app and jailbreak our projector” and “you have to be fairly technical to jailbreak our projector”.

Also, the article is more about drawing parallels to the enterprise software security space (where the “Why?” is large-to-existentially-large financial and regulatory risk to an organization that gets hacked) than explaining why this specific projector should be more tamper-proof.

You think a 10 year old is checking the Shannon entropy of some files and deducing that that a single byte xor key is being used? Reversing it and adding more MP4 files then writing NFC cards to play whatever they want?

Surely this is a perfect example of a losing sight of the wider picture.

The articles appeal to well if they do this with a €10 projector they'd do it with a €100,000 is again absolutely comical.

		If you use rot13 as your data encryption, then a ten year old can absolutely break it--not by knowing what "rot13" or "data encryption" mean, but by clicking a button in a one-click jailbreak app. On the other hand, if you use stronger data protection, technical expertise can be required--remember the "kamikaze hack" for breaking hardware DRM on the Xbox 360? https://kotaku.com/one-of-the-wildest-console-hacks-ever-184...
