This should be a responsibility of those who run algorithms. As a data scientist and growth hacker, I have seen so many situation that a platform has been manipulated by a dark force of marketing. However, a response from leaderships are too underwhelming.
The study explains that is better to don't say that there are algorithms and not humans behind the marketing suggestion, but I agree that obviously who wrote and run the algorithms should be responsible for the wrong suggestions, but I would also say that must be indicate that "this ad/item is provided by an algorithm" and not by human. Transparency.
