Funnily enough the guy who invented MP3 earned enough from royalties to barely afford a regular house in Germany. Meanwhile Apple made billions and rose like a phoenix from the ashes thanks to Apple Music and the iPod that rely on this format.
The .m4a extension is commonly used for audio only MP4 (container) files. m4a files are capable of carrying other audio codecs other than AAC.
The .acc extension seems to mean very little. It indicates that the file contains a AAC stream but the container is not defined. Could be MP4, could be 3GP could be a raw AAC stream.
The concept of file extensions really break down when it comes to audio and video files. A single media file could contain a dozen audio streams in a dozen formats.
webm files really are nothing but mkv files in which the audio/video codecs are limited to a certain subset. You can “convert” a webm to a mkv by renaming the file.

Honestly anywhere other than windows they start getting a bit funky since most ecosystems don’t actually rely on the filename to determine the file type
It also doesn’t help that so many file types are just a bunch of text files shoved into a zip file wearing a mask. It’s all abstractions all the way down baby!
do you think would influence developers to make their projects open source, with more leaning towards copy left licenses? they won’t make much money off the code alone anyways, so might as well try to make others not profit either

Doesn’t the iPod use AAC?
iPhones use m4a these days for their native music app.
Sure, but they used AAC to rocket to success, not MP3. In fact, it was annoying back in the day because everything non-apple used MP3.
Aren’t AAC and m4a the same codec in different containers?
It’s really confusing.
