While I largely agree with you, I disagree on things like Google Play Music and Movies (includes TV). Their sales platform for other people's content works well. My wife and I used to use Spotify, a good service, but find a $15 / month family plan for YouTube Red (including Play Music) to be a good service and a good deal.

Off topic, but even though I have spent much of the last 30 years working on AI and machine learning, I did work for Disney and Nintendo for a while in the 1990s, and I have a keen amateur's interest in the business side of content production. I never would have predicted the amount of money Amazon, Hulu, Netflicks, and HBO would invest in producing their own content. Interesting that Google does not do the same thing. When I worked at Google as a contractor I enjoyed the visitor talks, and Spike Jone's talk about directing movies and the way he does it was very well received by a large crowd.

I am very glad that there are several large companies competing and not just one or two.

EDIT: I am all for decentralization and small groups/companies, but sadly we live in a world of larger corporations.
