^ Going on that video I think he did know it was not okay to buy them mate…
The guy somehow glossed over and omitted the part of ‘Fan Edits must never be bought or sold’ on his video (around 7 mins in) - despite talking about what was on screen in detail before that particular line of text.
He also linked to the site - so he is very much aware that fan edits and preservations etc must never be bought and sold - and also likely aware that Harmy even made a video on the very subject, here:-
Yeah you’re probably right, maybe I just want to see the good in Star Wars fans all the time haha
