I think the article is a little on the paranoid side.
The case in question is about textbooks. Some publishers will take the fancy hard-cover textbook they sell for an outrageous price in the US and print it as a softcover on cheap paper for sale in Asia. I've bought one of those before myself.
Several outcomes strike me as more likely:
-Import restrictions are set up for particular editions of textbooks.
-Publishers stop gouging US students and start making the same softcover editions available to US students.
-Publishers stop publishing cheap Asian editions.
The second option sort of makes sense in that there may be more money in selling two cheap copies (which might be in unsellable condition by the time the semester is over) than there is in selling one hardcover (that will be resold by the campus bookstore). But then again, some students might prefer new textbooks, others might prefer to hold on to them forever instead of selling them in the delusion that they might be useful again some day ( 😊 ), and of course the publisher can always come out with a new edition and make the previous edition redundant and effectively unsellable.
