FAT32 is also really simple to implement. Supporting exFAT may require a larger microcontroller with more memory, which results in a more expensive product.

I personally haven't had to touch it in over a decade, but I guess there's probably some uses for it still, yeah.

Yep, many smart TVs still only accept FAT32 format. I have to split my HDR videos into multiple files to be able to watch them on TV — because of 4GiB size limit.
