The NTFS3 driver withdraws the write right from such files with the READONLY
attribute:
$ ls -al /mnt/Daten/Users/Praxis/

The partition was statically mounted by /etc/fstab:
$ findmnt --type ntfs3
TARGET SOURCE FSTYPE OPTIONS
/mnt/Daten /dev/sda7 ntfs3
rw,relatime,uid=1000,gid=1000,dmask=0002,fmask=0113,discard,nohidden,hide_dot_files,windows_names,iocharset=utf8
I see no possibility to have drwxrwxr-x instead dr-xr-xr-x for e.g.
folder "Documents". So it is impossible to add new files to such
folders. Theoretically it's possible to remove the READONLY attributes
from Windows side, but this would be a security risk for Windows.
On Windows, attribute READONLY does not prevent from adding files to
such folders, it only prevents from renaming and deleting the folder
itself, but the withdrawal of 'w' in Linux results in the opposite, it
prevents from adding files, but allows renaming and deleting the
folder itself. So the NTFS3 simulation of access rights is wrong here.
My suggestion:
With attribute R on a folder NTFS3 should only prevent from deleting and
renaming somehow, maybe by simulating a suitable posix ACL, but enable 'w'.
