Excellent article. That these practices still abound points to lazy thinking & ignorance!
I have myself been a victim of this kind of quackery.
At my first job after graduation, after about 6 months, my boss began giving me a really hard time & virtually bullied me over the next two to three months until I found another job & quit. (This was many years ago, when correspondence was still by letter / snail mail).
During my exit interview, I found out the reason for my Boss' stupidity.
Apparently a supplier in Germany had told him that my signature on correspondence was too small & that meant I would not contribute to the Company as I would be too timid, lack confidence & not accomplish anything major.
I wish it had happened recently : I could have sued the guys' pants off (which would still be small concession to the grief I underwent!
Which brings me to my conviction that today we have many "Educated" people who are just not learned enough - people of letters who can't put them together to form words.
