Again, many of these arguments are not "unique" to Matzinger as if he is inventing them or something, they are plain to see for linguists and have been known about since forever:
"It is clear that in the Middle Ages the Albanians extended farther north; that there are persuasive arguments which have been advanced against their having extended as far as the Adriatic coast — the fact that Scodra 'Scutari' (Shkodër) shows un-Albanian development, that there is no demonstrated old maritime vocabulary (see above), and that there are few ancient Greek loans; and that there are arguments in favor of old Dardania: Nish < Naíssos, with development as in pyll 'forest' < *pëýll < *padle(m) < *palūdem,"

So this attempt to try pile on one linguist because he is arguing for clear mismatch between the phonological systems of two languages as if he is the only one that is noticing, is futile.
Finding a word here or there even if related isn't going to change the phonological system mismatch, as this is what determines descent in linguistics.
Illyrian and Albanian will have cognates, probably more than Albanian and Celtic, this is to be expected just from geographical proximity alone, but their phonological systems are not matching according to countless linguists now, and this is why they are argued to not descend from one another.
