I don’t really see the benefit of allowing users to create files with the same name in the same directory, yeah, yeah I know that case sensitivity means that it isn’t same name, but imagine talking to a user, guiding them to open the file /tmp/doc/File and they open /tmp/doc/file instead
The reason, I suspect, is fundamentally because there’s no relationship between the uppercase and lowercase characters unless someone goes out of their way to create it. That requires that the filesystem contain knowledge of the alphabet, which might work if all you wanted was to handle ASCII in American English, but isn’t good for a system which needs to support the whole world.
In fact, the UNIX filesystem isn’t ASCII. It’s also not unicode. UNIX uses arbitrary byte strings, with special significance given to a very small number of bytes (just ‘/’ and ‘\0’, I think). That means people are free to label files in whatever way they like, and their terminals or other applications are free to render them in whatever way seems appropriate, without the filesystem having to understand unicode.
Adding case insensitivity would therefore actually be significant and unnecessary complexity to add to the filesystem drivers, and we’d probably take a big step backwards in support for other languages
macOS also does this by default, but you can change it (though you have to reformat the disk in question). This is generally fine for non-system disks if you REALLY need it for some reason, but afaik it is not recommended for the OS disk due to assumptions that macOS-targeted binaries make (similar to the windows regex version matching that caused problems for a while because it became the unofficial best way to check windows versions for app install compatibility). It’s doubly annoying on newer Apple systems because the integrated SSDs are WAY faster than pretty much anything else you can connect to it. But for the most part, I find it’s more of a nuisance to keep in mind than a real problem (I’ve been dealing with dev-issue MBPs since about 2012).
As in the windows case, this is also an appropriate choice for the average Apple user (though the fact that they’re fairly ubiquitous as dev machines in many places is annoying on several levels, despite the generally solid best-case performance and thermals I’ve observed).
Just checked on my work box - if you go into Disk Utility and start the process to add a volume, the default selection is APFS, and there’s an option in the dropdown for for APFS (Case-sensitive)
This isn’t “Windows design”… this is just inherited stone age bullshit from the DOS days when the filesystem was FAT16 and all file names were uppercase 8.3.
NTFS is case sensitive in its underlying design, but was made case insensitive by default, yet case preserving, for reasons of backwards compatibility.
If Microsoft has to design something from scratch, without the need for backwards compatibility, they go for case sensitive themselves. For example: Azure Blob Storage has case sensitive file names.
If you rename a file only changing the casing it doesn’t update properly, you need to rename it to something else and back.
This is so userfriendly I have been stumped by it multiple times.
On the other hand in using Linux I have had a number of problems with the casing of files: The number is 0

To my great surprise, this has been fixed. I don’t know when, but I tried it on my Windows 10 VM and it just worked. Only took them 20 years or so :)
This is one case where I think Windows is appropriately designed for its target audience.

Huh I had thought case-sensitive was default on APFS/HPFS and you had to choose insensitive specifically but I guess not
