Surely the man whose most well known trait is how much he lies can be believed
That's called doublespeak
Wait, those are a thing?
Mounting locations are a convention, not a standard, mount whatever you like wherever you like. In your case, I'd mount it under /mnt/ntfs, /mnt/windows if it a windows main partition you want visible, or by drive letter if it's a secondary drive on a dual-boot system.
Or however you want. I would keep it under /mnt, but you don't have to.
Do maybe sure you have user permissions set up properly if this is a multiuser machine though
Edit: also I would interpret
If /mnt is for temporary
'temporary' as in 'may become unmounted without seriously fucking the system'
/ and /home aren't temporary. Everywhere else is
I wonder how many of the people following it are taking them as recommendations instead of warnings
I'm sure the archaea in the salt flats will adapt too
