Maybe it's as simple as flash memory corruption on the guy's phone, the photo of mostly table and just the edge of the envelope is "simpler" (lots of the table which is just white), so maybe it takes less space. The more complicated photo would take more storage space, what if it's hitting a bad block or a period of bad blocks because of the physical memory layout (e.g. a sequence of bytes every 4MB is bad).
Your explanations appear less likely, as I’d expect those types of bugs to show differently.
There’s plenty of evidence for „conspiracies“ similar to what’s suggested here - Eurion dots are absolutely real. That doesn’t mean that I believe they’re being employed here, but it seems like a good candidate for further inspection, especially because it‘s a hypothesis that is fairly easy to test.
Please, my mind is open, but as others have explained it's probably some image format being misinterpreted. To immediately put as prime suspect a theoretical secret government mandated software when a harmless photo of not-a-secret-document is corrupted is... nutjob-level insane.
If my car breaks down should I think "Oh shit the CIA/KGB/etc must've beamed a signal down from their satellite to jam my car's ECU", or should I wonder what part wore out? Original poster assumed the first with his "censored", while I'd like to explain there are a lot of possible harmless explanations. If someone's done a proper investigation and found censorship software, well I'll be damned, but before that, I'm not going to think "the men in black are out to get us!". People who think like that used to be found yelling on street corners, now they're all over the fucking Internet.
Read this to see why your brain maybe finds it more exciting to think it's a conspiracy: https://www.thestreet.com/phildavis/news/a-game-designers-an...
