Another theory: OCR scanning technology back-engineered from 1960s movie about little alien mutants with glazed bug-eyes -- "Village of the Danned"
In 1977 OCR technoloyg could BARELY do proportional font scanning. I know, I was writing hand-crafted PDP-8 assembler to do it. OCR would not convert a document to proportional fonts.
All this is just hilariously desperate. They are such public school victims they don't even know the history of technology in their own lifespans.
