Sure, Google can revoke my access to a movie at any time but I can watch on any of my devices and I dont have to worry about finding it in stock at the local store.
I can carry literally thousands of books with me in a device smaller than a paperback.
I can’t stream lossless music from Spotify but I can stream high enough quality that most people can’t tell the difference. Not to mention you get access to pretty much every song you want for 10$ a month.
Electron apps and the web are replacing desktop apps but they are also making it easier than ever to make a cross platform app, meaning we will get apps that we otherwise wouldn’t. This is especially good for Linux, which would be much further behind macOS and windows without popular electron/web apps available like slack, Spotify, etc.
