Years ago, some historian was griping he could not get his review of a book on the Vietnam war onto Amazon (one of the historical personages was named “Phuc” and the algorithm kept kicking it out).
His main complaint was that there was no recourse - writing to Amazon just generated form letters in return, there was no-one to call, etc.
We’ve come a long way from such accidental/incidental censorship to full-blown Orwell.
