This just brings me one step closer to dumping Apple Music, and eventually all and any of iCloud subscriptions.
Don't get me wrong - I actually really like Apple Music, but they can't get iCloud sharing working, and their storage pricing is more expensive than anyone else's. If I can have all of my music and photos on either Amazon or google, AND link up a few echo dots (Linked to existing speakers) throughout my house, and share photo storage with my wife a la google, and get massive shareable collaborative storage from office 365 (1TB for each of us), then why am I paying for iCloud again? Sure, I can share a file with my wife, but she has to share it back to me if she does any work on it.
The Homepod doesn't even come into it for me. I have speakers, and they're cheaper than the homepod anyway.
