Ultimately, RAW formats aren't that complex, and camera firmware is mostly developed in countries that don't have strong open source software traditions.
It's some binary parsing, reading metadata, maybe doing some decompression-- a thousand lines of C++ on average for each format. These aren't complex codecs like HEVC and only reach JPEG complexity by embedding them as thumbnails!
Cameras absolutely could emit DNG instead, but that would require more development friction: coordination (with Adobe), potentially a language barrier, and potentially making it harder to do experimental features.
Photographers rarely care, so it doesn't appreciably impact sales. Raw processing software packages have generally good support available soon after new cameras are released.
I did push for all my digital images to be DNG, and they are, up to around 2018, and two out of four cameras use it natively - Pentax, Leica - while the other two use their own formats - Canon, Fuji.
The reason I’m less fussy now is because the combination of edits, metadata and image data in a single file didn’t necessarily help me when I switched from Lightroom to Capture One. I would love to be able to update the files to use newer RAW processors and better IQ, but I lose the Lightroom edit information in C1. That makes sense as they do things differently. But I hoped that with DNG there was a universal format for handling edits.
My JPEGs remain the definitive version of the images but I would love to be able to recover all those original edits again in C1, or any other editing program.

Look at the decoders for each format that darktable supports here: https://github.com/darktable-org/rawspeed/tree/develop/src/l...
