Hello,
I've noticed the fsType value in the OS/2 table of OTF fonts is not honored by Indesign nor Illustrator.

I've set the value of fsType to 0x0102 and this should prevent subsetting and embedding.
However, Illustrator exports to pdf, embedding . Worst, it gives no warning the embedding/subsetting isn't allowed for the current font.

for info, I had flushed any font cache to be sure the font files are the good ones and deleted them from my disk before reopening my pdf to be sure they're embedded.
For info, these fonts are located in Library > Application support > Adobe > fonts

Mac Os. 10.14.6
Illustrator 24.1.2
