You'll forgive me my cynicism; the lack of notation regarding the OGL on those pages, despite it being central to the topic, struck me as an omission that was hard to make on accident. My bad if I misread you.
I'll point out that I did
grant the premise that's not a fallacy if an actual expert is being cited (in the post right before your own); I just pointed out that this was
not the case
here, since neither of those webpages connote any expertise (or even knowledge) where the OGL is concerned, and so the charge of them being fallaciously cited as authorities
in that regard is entirely warranted.
