There have been windows drivers for Linux filesystems for a long time. I never dared to let windows read my Linux disks back when I still used it from time to time. Never trusted it enough for that.
When I first installed a distribution where the base system only came with nano instead of standard editors, I was very confused (and very disappointed that this whas what they'd come up with as a "friendly" interface).
Didn't expect to find another CV1 usr in the wild.
I wish there was a way to use bottles or whatever to use the damn thing until an affordable and usable replacement finally appears.
