Agree, but these are not just demoscene fonts, for example I also found the fonts from the original Lemmings game(s) (https://github.com/ianhan/BitmapFonts/blob/main/lemblue.png) which were of course part of a commercial project. But as the games themselves are available as "abandonware" on various sites and Sony (who is sitting on the rights to the Lemmings franchise and not doing much with it) hasn't objected to that yet, I wouldn't worry too much...
