That isn't true. You need to use ntfs-3g, which is a free software implementation of NTFS (that allows both reading and writing). It's been stable for 10 years. Using NTFS doesn't require anything from windows and doesn't require proprietary software.
I just downloaded the source for ntfs-3g[1], and it doesn't appear to have any binary blobs in it. In addition, it's under the GPLv2 so integrating proprietary components is unlikely to be legal. The answer you linked quite clearly says that the company offers a proprietary version of ntfs-3g. The answer does not say that ntfs-3g is proprietary.
Also, Trisquel (an FSF-approved GNU/Linux distribtion, meaning that it doesn't have any proprietary software within 100km of the distro) has packages for ntfs-3g[2]. So it's _definitely_ entirely free software.
So again, you're wrong on this point. In addition, I strongly believe that you were never correct on this point. Maybe you confused ntfs-3g with the proprietary version that company sells?
I know there was a way to write to ntfs from Linux, but it required to install ntfs driver file from Windows.
I hope there is a native ntfs support that supports writing.
