You know who used to do that? Microsoft Teams. I would take photos with my phone and upload them via Teams, Teams would display them just fine but saving them teams would name them .png (even though they were jpeg) and I couldn’t open them with the gnome image viewer (this is also how I found out that the image viewer prioritizes extension over magic byte (which seems stupid to me).
that would be renaming the file extension but keeping the same format opening it up in an app that breaks it totally, then saving that and sharing it with a Windows user and spending an hour with them trying to make it work because they have to see it!!!
That has to be Chaotic Evil.

You’ll quickly learn which software trusts extensions and which uses MIME type detection
I still laugh at learning that some random files in my friends Factorio mod were misnamed when Factorio changed the library they used in 2.0
