Sentence three is naive...
"We also provide evidence regarding the origin of the writing system of this manuscript: it appears to be a late modified subset of a once widespread shorthand known as Tironian Notes."
There's no evidence that any of the Voynich characters are derived from Tironian notes. Countless researchers have looked at Tironian Notes. I spent quite a bit of time learning parts of the system to make sure I understood it correctly before having any opinions on it.
The "odd" characters in the VMS, like EVA-y, EVA-m, EVA-g, etc., are Latin scribal abbreviations and only very weakly similar to Tironian notes. They are essentially copies or adaptations of the early Greek scribal abbreviations (some are identical to the old Greek conventions). The gallows characters are more similar to Latin ligatures and Greek numerals than they are to Tironian notes.
They must not have understood Tironian notes very well when they wrote the paper. The concepts of Tironian notes are still with us, in various adapations of shorthand that occurred from the medieval period to the present, and they do not resemble the VMS any more than the original Tironian notes.
