The examples in this blog are of online streaming media changing from a wide searchable library to an unsearchable tailored recommendation feed.
As I understand, licensing dynamics were the main reason for Netflix's change, not pure product design. In 2012, most movie studios licensed their catalog to Netflix, while 7 years later they took away the licensing to compete with proprietary walled streaming platforms. Due to the smaller catalog, Netflix could not design that open searchable streaming library; they changed their design to make the best of the more limited library.
