I think what the article is missing is that main issue with streaming platform (for music and videos) is that it reshapes completely the business models of the music/movie industry. A CD or DVD was maybe a bad product, but it allows not "TOP" artists/production to still get ROI without needing to be viewed/watched by audience of billions.

The music/movie industry is now way less diverse, because smaller actors cannot live out of it, so only the big players remain and produce stuff that only a very large audience would like but not love (you cannot please everyone whenyou have a 1B audience). Smaller categories in movies and music will just disappear: look at the 2000`s movies like the Ninth gate or some cool thriller, these could not make enough money just with the theater tickets but they could exist thanks to the DVD money. Now with streaming there is not enough revenue to capitalize on second tier movies (not block busters) that would be really loved by a smaller audience.

We have a less fragmented culture so by definition it just slowly looses its richness.
