There are some opinions for this video in Japan. Because this video is too much emphasising that any data handling on marketing must be wrong. But those opinions are mostly in side of marketing and tech company side who are dealing with online marketing. Recent all of marketing activity are heavily depending on user data analysis by associated with user’s IDs. The perspective of consumer is not well considered than company side benefit. It’s unbalance between consumer and business in last decade tech development. This is a part of reason I left from the industry.
In fact, the online tech company is also caring the privacy protection by anonymising, so not bidding by persona name basis in the video. But at same time, regardless online or offline, there are some hidden trade about no anonymised persona data as violating the law, so platform vender should make function to protect user from at least criminal, also making well balanced system between consumer and business. So I can agree with the video and apple’s direction on this topics.
